Not meaning O’Doulls because there is a little bit of alcohol in that. I mean like a juice, an energy drink, a soda, anything like that.

No. Even if something started to ferment then it would have alcohol in it.

Now people do have different reactions to different things. Some need quite a bit of caffeine to get going and some are real jumpy and jittery with just the slightest amount. Maybe a particular ingredient may have an affect on you or someone else that it does not have on others but that does not mean you are drunk.

Too much caffeine will have the opposite effect. Caffeine dehydrates. If you are dehydrated you will feel tired and lethargic. It is our body’s way of trying to keep from over working and overheating. Try 2 glasses of water and watch the improvement if this happens.
