Actavis vs Mercury T4

Hi I have been on Mercury T4 for 20 months or so, but my latest prescription was Activis ( apparently they couldn't get Mercury). Ive been taking it for 2 days and today I am feeling really hyper. Could it be the different brand? I really don't want to start mucking about with my dose.

However I am 2 weeks into a GF diet and am adding lots of vitamins etc. Maybe I'm just getting more sensitive to the T4? Or converting better? Any ideas? Thanks!

I felt the reverse!

Mercury Pharma makes me feel slightly over-dosed shortly after taking it - but under-dosed by the time I am due my next tablet. Actavis left me feeling permanently slightly under-dosed.

(I ended up adding 12 micrograms of another make to 100 micrograms of Actavis - and that has been pretty good!)

But, the important bit, yes - a change of make can make a substantial difference to some people, whilst others notice nothing, or a change in the opposite direction.

Other changes such as you described can also have effects.

Thanks Helvella, Thats interesting. Not very helpful though! Ha Ha!

There is alot going on so I will give it a few days. Also, often a bit of a delayed reaction as you say. Thank you!
