The biggest thing for me is if I have a caffinated beverage later in the day (say after noon, but especially with dinner), it becomes a lot harder to fall asleep. This can be subtle, but like was tired all day and had a cola with dinner and now can't go to sleep is a pattern.

But yeah, if I drink a Trente anything from Starbucks, there's a whole lot of caffine in there and I feel jittery and uncomfortable, and there's nothing to do about it other than wait and maybe drink extra water and hope that helps.
