I would really like some help with this. Byetta has been wonderful so far, and I've lost 30 lbs, yay! But now I've developed insomnia - terrible, only 3 hours of sleep a night insomnia, which has never bothered me before. If I skip my second Byetta shot for the day, I can usually get a full night's sleep. So that's certainly a clue that I may not be able to take the full two doses of Byetta a day.
