I have hypothyroidism also, I've been taking the levothyroxine for about a month. The only way I can take it with the food restrictions is to take it first thing when I get up. Otherwise, there is no way through the day where I can go 3+ hrs without eating. My body just won't let me.

I haven't noticed a huge difference in how I feel yet, but the Doctor started me on the lowest dose and just rechecked it today, so the dose may be going up. Hopefully I feel better then. We'll see.

Oh, and I've also heard of the carpal tunnel like symptoms from low thyroid. Can't remember what causes it though.
