I have been taking Synthroid since Jan. 2006, am on 100mcg per day and all test results have been 'normal', I have been told to take this medication in the morning an hour before eating anything, if I do this...I have headache all day, I can't eat after an hour because I am so sick at my stomach there's no way. I feel hungry, but feel like if I eat it's coming right back up. Am having serious joint pain in hips, knees, elbows and wrists, my neck hurts really bad as well. I wake up to arms asleep anymore and just feel like I haven't slept in months...am very weak and very tired all of the time. I have found that if I take my pill at night this gets a little better, but holy cow, don't tell your Dr. your taking it before bed...no, take it of a day. (don't know why this is a major thing?) Anymore I feel like I am walking around with flu symptoms constantly, and the Synthroid hasn't done anything weight wise with me, because I was so HYPERthyroid before the RAI, I was very thin and looked like a bag of bones, have been waiting and excited about putting on weight...at one point I stopped taking the Synthroid and let myself go HYPO just so I could gain weight, it worked and I got up to about 130 pounds, was very HYPO so they told me critical that I get back on meds...I lost it again because it makes me so sick I can't eat. NO-ONE can tell me the Synthroid is not the cause of this problem, if I stop taking it I feel WONDERFUL, but my test reults are bad. After a while of course my feet become numb and I end up having some bad hypo symptoms, have tried breaking pills in half....oh Lord no, need it all... Have been told they are thinking about raising my dosage again anyway, I can't do this, I will break down in the office if they try to raise it. Right now my TSH is fine but my T4 is 'a tad bit' off. I am already an emotional wreck, if they raise my dosage I am going to try and go a different route with this, am on my 3rd Dr. at this point anyway...
