I've been working with a helpful doctor to trial some t3 and I'm definitely finding it beneficial during the day. Then at night I have no difficulty getting to sleep, but about 3 hours after getting to sleep, I'm suddenly wide awake and can't seem to hold still. If I try to stay in bed, I'll be restlessly writhing around for hours. If I get up and have some carbohydrate then I can usually come right back and be asleep again within 15 minutes. This never happens when I'm not taking T3. Any idea what is going on with me?
