Hi, guys I am desperately in need of some sound advice. I have a question re the thyroid gland... I did something a couple of weeks ago that I now sorely regret - in an attempt to lose weight I took cytomel T3 @ 25mg a day for 5 days then did one day of 50mg and it gave me palpatations and insomnia so the next day I reduced it to 37.5mg, but still had insomnia, so the nest day I reduced it to 25mg which i took for a further 3 days, then I did two days at 12.5mg, then two days at 6.25mg. When I came off it I felt lethargic, my hair went dry and then I got a sensation of having lump in my throat which felt exactly the same as the one you get when you are going to cry! I have been off the cytomel for a week now and have gained weight, feel tired and have the lump in my throat... I have read that these are all symptoms of hypothyroidism, and that sometimes after using cytomel T3 there can be a rebound effect. I am really worried that I have screwed up my thyroid, but don't know if it is purely a rebound effect. If it is rebound how long should it approximately last, and how long should I leave it before I see my doctor? I don't want to tell my doctor what I have done, so I need to be sure that it is not rebound, otherwise he will test my thyroid and then treat me for hypothyroidism when I don't actually need it which could really screw me up. I am really really scared and feel very depressed, any advice you can offer is greatly appreciated. Cheers
