Mandy72, I do realise you are sick and tired as you've been through so much trauma with regards to getting your hormone replacements right for you.

First 40mcg T3 doesn't mean your pulse shoots straight up within a couple of hours. 40mcg has the equivalent effect of around 150mcg of levo up to about 200mcg so it's not too high. It's average.

When we've been quite unwell it takes some time for our pulse to become 'normalish' i.e. around 60/65 bpm. My husband's pulse (doesn't have hypo is around 32bpm) mine varies between 62 and 65. When hypo it was around 50bpm

If we aren't aware of what our 'healthy' pulse was it is a bit of a guessing game.

It's best if we stick to a change in dose of whatever hormones we take for quite a number of weeks to see what the effect is on our body. Our bodies have been struggling long enough for want of sufficient thyroid hormones so it is going to take a while (for some of us) and I do know you have an awful time and I wouldn't wish it on anyone. Changing too often may mean we are on a round-about and cannot get stable.

If you are taking 40mcg over the next 7 days, I'd take pulse before you get out of bed. This is an excerpt from a previous thread:-

I have been Hypo for 27yrs and my heart rate has always been between 47-54, I am ok but walking up slight inclines makes me ridiculously breathless. Am on 125 Levo,, cannot lose weight. Have started going to the Gym, this is my second week and always eat a healthy diet as also type 1 diabetes (with insulin pump) and have only lost a 1lb. Disheartening to say the least.

Hi Mandy72,

This is just some information from Dr L. It might not make much sense (it's a bit clinical for me) but is re T3 and temp:-

1. Dr. Wilson has it backward: T3 doesn’t Increase enzyme activity by raising the body temperature; instead, it’s the other way around: T3 increases gene transcription for enzymes (such as sodium-potassium-ATPase), and the resulting increased enzyme activity raises the body temperature. The enzymes do this by cleaving phosphates off ATP molecules. The cleaving releases the energy that was maintaining the phosphate bonds. About half the energy is used to fuel chemical reactions. The other half is released as body heat

thats really interesting Shaws

i cannot cool down

as soon as hubby has left for work the windows are opened and the fan is turned on blowing on me

at night hes complained its too cold and has pulled the window shut a bit but i still have the fan blowing on me, sitting in the car i have to have the window wide opn and he complains its cold

in the evenings hes saying it codd and asks me to turn off the fan, i have to move it so its not blowing on him at all

other than that i still feel awful, no energy, hardly sleeping on 6mg melatonin

short of breath, water retention, brain fog ( i can be sat doing something and forget how to do it), i ache, headaches

in the evenings my eyes get very watery and itchy (looks like im crying) but they allso feel really dry at the same time

heart rate increases in the evening to the point i have to take my beta blocker

mood is awful, one minute im ok and the next its like ive been possessed and i dont care whos around (happened in tesco last week)

Sorry for late reply as I'm away from home at present. It does sound as you aren't on sufficient hormones but I wonder (just a thought) if you've not already tried another T3, it might be worth it. I developed symptoms after I was on MP T3 for a while and it wasn't until others complained and I put a report in to the MHRA (I think) that I changed and that T3 suits me very well and I've had no bad symptoms since. Sometimes it could be the fillers/binders that affect us. By the way, MP said that there was nothing wrong with their T3 but T3 itself should cause problems but the fillers/binders might not suit our particular bodies.
