My thyroid nightmare started about 4 years ago. I was gaining weight at a rapid rate (I gained 30lbs in a year) I could not even stay awake in the car, let alone get up in the morning. I started out on Synthroid .5. I have been sort of yo yoing around for the past few years and am now on Levoxyl 137Mcg. It seems to be working for now. What I would like to know is how to keep it level. Mine seems to go out of wack all of the time. I have problems with hair loss on and off, but it seems more so lately. I would not say I am feeling a ton better, but much better than before. Weight loss is slower than most people, but it is still coming off.
