Cytomel is T3. Most people start on a T4 drug like Synthroid or Levoxyl. (In fact, most doctors even refuse to prescribe T3 at all.) It isn't that any one of them is "better"; just different. There is no one size fits all.

It could be you don't even need T3 and that could be why you have sleep problems. You need to have your FT4 and FT3 levels checked to see what your thyroid hormone needs are. A TSH test doesn't cut it once you're in treatment. A doctor who treats based on TSH alone doesn't know what he's doing.

As for your last question, it does take a fair amount of tweaking to find a person's best brand/dose in the vast majority of cases. Dosing is an art more than a science.
