i've been working out at night after dinner (because i gotta work during the day). i've just started taking ON 100% whey, for pre-workout (whey+oats) and post-workout (whey+glucolin+oats).

however, during the night, i'm having real trouble sleeping, like getting a really good rest. it's either i take a really long time to fall asleep or i'll wake up after 5 hours or so automatically and will have trouble going back to sleep again.

i think i've pretty much narrowed it down to the whey, as i've worked out before during the night without whey intake for pre and post workout, and i had no trouble sleeping. also i've tried eliminating glucolin and the oats from the equation to see if they were the ones causing this, and i still have the same problem.

on days when i don't consume whey, i sleep perfectly. so it seems like the whey is causing this.
the whey flavour that i'm consuming at the moment is cookies and cream.

is this common?
