Given your symptoms and your TSH level, which is well above the revised range of .3-3.0, it appears that the medication is in the right direction. When you go back in 3 months, or less, you might also suggest that the testing include Free T3 and Free T4. If you want to get an indication of your thyroid state right now, check your temperature for several times a day and for several days, in order to get a good average result. The normal is reported to be 98.6, so anything below that is an indication of low metabolism/ low thyroid. If you want to do some reading about these things, try this site.
