Insomnia is a side effect I hadn't heard about! Interesting! I've mostly just had the occasional nausea, and burping.
I realized this week I went dancing tonight (Tuesday), have a meeting for the dance programming committee tomorrow, Thursday I am DJing, Friday I am dancing, and Saturday I am DJing. No wonder I feel like there's too much dancing stuff going on! (Thankfully next week it'll be back to our usual just twice a week, not five times!)
