Overdose

As far as I am aware you cannot overdose on B12. Some people do have reactions to the other ingredients in the injections - which can amount to anaphalactic shock so it may be worth looking at whether you are sensitive to any of the other ingredients.

Also, during early stages of treatment your potassium levels can be affected - they can fall - hypokalaemia - symptoms of which include dizziness, general weakness, muscle pain and tiredness. Has your doctor monitored your potassium levels at all?

Following is a section from CDC (US) site on B12deficiency

cdc.gov/ncbddd/b12/patients...

Vitamin B12 is considered safe, even at levels much higher than the recommended dose. It has not been shown to be toxic or cause cancer, birth defects, or mutations.10,75 Be aware, however, that patients who have a vitamin B12 deficiency with associated megaloblastic anemia might experience hypokalemia and fluid overload early in treatment due to increased erythropoiesis, cellular uptake of potassium, and increased blood volume.

Some people also experience problems with acne and rashes but that seems to be an initial response as the B12 starts to work and seems to go away with time once levels have been properly stabilised.

On the not sleeping - I find it difficult to sleep if my B12 levels drop and taking some B12 (nasal spray) helps me sleep/get back to sleep. If my B12 levels are low then I also have problems with diarrhoea and I certainly have a lot of problems with 'gas' - though I find that some pro-biotic yoghurt each day seems to help with that .... besides making sure that I get some calcium - love cheese but not a fan of milk.

Its really difficult to say when you will feel better because people vary so much when it comes to B12. It also depends on what your symptoms are and if you are being treated with the right format of B12 for you and at the right doses.

I went backwards in the first 15 months of treatment but then started treating myself with much higher doses (the nasal spray I referred to) and problems resolved themselves quite quickly but I don't know exactly how deficient I was before treatment started - have been unable to get hold of a copy of the blood test that identified B12 deficiency.

Hope that you start to feel better soon.

Potassium count is good. Don't think ingredients in shots had anything to do with dizziness because half shots are not making me dizzy. Saw a video on Internet a while ago and that person said she got dizzy when her B12 went high from to many shots. My sleep has always been awful but now if I don't get at least five hours of sleep I usually get the diaherra. Last night got 3 1/2 hours of sleep and have been in the bathroom 7 times. And still when I try to nap I can't fall asleep. Do most people who get the diaherra take pills to stop it or do they wait for it to stop on it's own? So tired feeling like I have the flu. Also, legs have been hurting me when I try to sleep.

I've had tummy problems with PA too.The only thing that has helped me with that is a water-based probiotic called SYMPROVE -Unfortunately expensive, but worth every penny to me. Apparently PA can cause low gastric acid so food does not digest properly. Instead it ferments, causing tummy pain and belching. The pro biotics help to sooth the stomach, and helps good bacteria to get the upper hand. As regards the dizziness, I had that when my B12 serum count was 150, but injections solved it . Sorry I can't help on that. As regards sleeping, I just read in a German book that B12 is needed to make Melatonin ,which in turn is needed for good sleep. But it takes some time to establish good sleep patterns. Are you taking a good Vitamin B complex with the folate(B9) as METAFOLIN not FOLIC ACID? You need them for proper utilisation of B12. Or best of all eat plenty of green leafy veg, some raw e.g. watercress. Peas are also good. I hope that I have helped a little. There are lots of people out there with better knowledge than me, and I am sure that you will eventually hear from them. The very best of luck to you,and I hope that you will be able get back to your job.

I find I feel jittery/palpitations if I've had too much B12. I've discovered the kind of B12 makes a huge difference in how I feel. Here in the United States my doctor only provides cyanoB12 which is felt to be the worst option, so I've been handling this on my own with injectable cyanoB12 only as a backup.

The hydroxoB12 nasal spray from detoxpeople (they ship to the US) seems particularly strong and I was jittery for a couple of days after applying in both nostrils. Next time I'll only do one side for a 500 mcg dose.

I also obtained methylB12 for SC injection. I've found injecting 250 mcg to be about right. It's easier to more precisely control the amount injected than with the nasal.

I've been taking digestive enzymes with meals particularly when I'm having meat. Contains Betaine HCl to replace stomach acid, plus other enzymes. I believe it helps, though today I do have some stomach pain. Sometimes I wonder whether my stomach lining keeps trying to regenerate itself and the pain is the IF antibodies destroying it as I seem to get tummy pain in cycles.

Like Tracy, I've found enzymes helpful with digestive issues too, currently taking Bromelain. I was taking Betaine, but found there was gluten in the tablet which I also avoid. Since stopping gluten, I've mostly stopped vomiting. Also had to stop drinking tap water (get a severe burning sensation in stomach after a few glasses) and eating spicy, fatty or acidic food. Can't take aspirin or NSAIDs.

Hi Wienke. Are you sure there isn't some other problem here? It may merely be a coincidence that this has coincided with you getting a shot. Perhaps you should get a coeliac test? You don't say why you have low B12 to start with. Could there be a coeliac problem underlying this?

Hi,

Hope these links might explain about coeliac disease (celiac on USA sites).
