Hypo here... for 7-8 years. Diagnosed at a routine physical shortly after my older sister was diagnosed with a goiter. Mainly was seeing my family practitioner, then the reproductive endo (for atypical PCOS), then the OB once I was pregnant and back to the family prac. So, in all that whirlwind of switching providers I was going through many dose changes/thyroid swings. I finally asked for a referral to an endocrinologist and he has been wonderful!
The biggest change was telling me to make up missed doses. With two kids under three I was missing 1-2 pills per week. The family doc said just skip them if you don't remember until the next day. He said take the missed doses as soon as you realize they were missed - up to three at a time. Also he was much more open to keeping me at the low end of normal for TSH. Family doc said as long as it is in the lab's normal range you are fine (TSH up to 5!)
I do still feel like crap, but I have a 3 yo, nursing an 18 mo and pregnant, so I suppose I can't expect to feel all wonderful
Also have been running kind of hyper lately (TSH <0.2) which they want for pregnancy, but it interferes with sleep, so am I tired from the kids, the pregnancy or just not sleeping well??
Anyway, to add on to a few of the earlier comments. The endo says to use Sythroid, Levoxyl or Levothroid ONLY and stick with one of them. The problem with the generics isn't so much that they are bad, but that you need to stay on the same brand. Once you say generic is OK, you may get generic company A the first time then generic company B the next and so on and that can really mess things up.
I still have my tonsils and so does my sister, so I'm not sure of a connection there.
