same here, on week 3 now and feeling pretty good most days, yesterday was BAD though. I had the chocolate brownie for lunch and had so much gas and bloating from the sugar alcohol (I forgot how much is in those). Felt awful all day and into the night. Won't be buying those again.
Otherwise trying to keep as close to 100% as possible. Need to work on my water intake though.
