More caffeine than coffee? - two pepsis
I'm a huge coffee drinker and can drink cups of coffee before I go to bed without it keeping me awake. I seldom drink soda of any kind but a few nights ago I treated myself to a pizza and got Pepsi to go with it since when I do drink soda that's the only one I will drink. This particular night I decided that I was going to stay up past my usual 10:00 bedtime so I played spades until 11 and was drinking Pepsi while I was playing. At 11:00 I took my usual dose of Seroquel which usually knocks me right out. Not this time! I waited until 12:00 waiting for it to kick in but nothing was happening. I finally decided to get in bed thinking if I was comfortable that sleep would come. Nope...not even then! I tossed and turned all night basically sleeping off and on but never falling asleep for more than an hour. Do you think it was the Pepsi that kept me from sleeping? Does Pepsi have more caffeine than coffee does?
