Catrin,

Have you ever looked into whether you were having a T4 to T3 to conversion problem? I know some people don't do well with just T4 supplementation; they also need T3 supplementation, often through a combination drug like Armour. If you've had blood work done recently, you might want to if your T3 values are in the normal range or, if they are, if they're on the low end of normal. And if you're relying only on TSH, it often shows as normal, even if T3 is low.

Beyond that, you gotta take your drug every day!!! I hate to see you frustated about your weight only to read that you sometimes miss doses of your thyroid replacement.
