I have been on Levoxyl for 2 years. At first I lost weight, but then I started gaining and bloating like crazy. My doctor upped my does to 75 mg and that has made my hair fall out like crazy. I have bald spots on top. I am going to take myself off against my doctors orders. This is a horrible drug and should be taken off the market. Does anyone have any suggestions. If I do not take anything, I gain weight like crazy and am very tired. Please help. Send emails to bcioma@peoplepc.com Thanks.
