i was put on synthroid and was on it approximately 2 years then moved, my new doctor told me i didn t need it and took me off of it, no explanation or anything! i feel very tired , malaise and i find myself passing out at times wondering hat just happened and why??? it only last for few minutes, but it has me very concerned. i can t seem to make myself get up and do the simplest chores anymore, just like before they put me on synthroid! what is the problem, in your opinion???
