Well you certainly need levothyroxine. Make sure you keep getting tested every 6 weeks until your TSH is near to 1 because you've got quite a long way to go until you get in range and you don't want it to drag on.
Ask your GP to check vitamin levels B12, folate, ferritin and Vitamin D as you will most likely be deficient in all as a result of being so hypothyryoid. You need optimal vitamin levels to derive the benefit from levothryxoine.
Make sure you don't take any food or drink (except water) for an hour after you take your levothyroxine. If you take other medication or supplements, leave at least 4 hours.
I read your previous post and I'm very glad that you have now be given levothyroxine to replace what you are so desperately missing. Your poor thyroid has and is getting a real kicking.
I note that your previous blood tests over the years have indicated an above and out of range TSH. In a kind world you would have been put on thyroid replacement but for a reason that disgusts all of us the NHS/NICE or whoever deems that people shouldn't be treated until they attain a "score" of 10 (well in the UK), by which time a patient can be feeling utterly awful.
So now you begin your titration to find out your dose required. Others have given you advice on how to prepare for your blood draws over this period and I think it's prudent to say that you need to be a little prepared that levo can take a little time to do its job especially since you have had a struggling thyroid for some time. It needs to convert from its T4 state into the active T3 which will find its way to T3 receptors in cells all over your body. This is why the bloods are done every 6-8 weeks. Sadly it's not quite like antibiotics where you start feeling better in 5 days or so but you should start noticing that some things are improving and others are almost imperceptible. Over time you will find out how well your body can do this chemical magic trick of conversion and sometimes we need to help it along with getting mineral and vitamin levels in tip-top shape.
Many GP's are not fully conversant in this extra help we can do for ourselves as they are not really taught anything about it in med school, more a "well if your patient has a sluggish thyroid, give 'em the tablets and they wil be fine" attitude.
But you have come to the right place for any questions and just all sorts of advice and help from people who have been and are in the same boat.
In the meantime be kind to yourself , it's rather a lot to take onboard at first.
Great advice so far, just to add that with the high antibodies you may well find a gluten free diet very helpful although you may want to wait until you are on a regular dose of levothyoxine before tackling that element.
In addition to going gluten free to reduce those antibodies selenium is very good at helping with that as well. All the best for the journey to recovery though...
Prescribed iron tablets to take 3 times a day for iron anaemia, prescribed folic acid acid for the folate deficiency, given B12 loading injections but have been tested for pernicious anaemia first and given vitamin D loading injections thanks
