Hi all.I have been posting on here for nearly a year now since radio iodine treatment left me underactive and my doctor / endo put me on levothyroxine. I am a male in the U.K and have been put on ever increasing doses of levo (now between 125 and 150 mcg. I didn't react well at all to the Levo, it gave me awful itching plus the most debilitating insomnia ever (so bad I had to take days off work because of it and even sleeping pills wouldn't work!) and also my weight kept increasing even though I was told it would return to the pre thyroid stage when my thyroid had normalised. Such was my reaction to Levo I begged my GP to let me try NDT. He was very good and initially I tried Armour and then Naturethroid, finally finding WP Thyroid which suited me well as my sleep patterns have returned but the excess weight is still a problem. Unfortunately WP isn't being manufactured at the moment so in desperation I tried NP Thyroid but it gave me the same symptoms as the Levo. I have manage to source Liothyronine (Tiromel) 25mcg and have been taking this along with 50 mcg levo which has helped improve sleep quality but the weight isn't shifting despite either fasting, strict dieting, eating as normal, exercising vigorously or cutting back on the exercise. In my last post someone kindly told me where I could buy Naturethroid from without a prescription from the USA. I would obviously prefer WP but would like to try Naturethroid alongside the Liothyronine to see if I get better results. Can anyone advise me if I am doing things correctly as currently the only answers I get are on this forum but I do feel that I am using my body as a science experiment.
