Several people in my family are sensitive to caffeine. I can't sleep if I have coffee in the afternoon, and dad won't even each chocolate.
A few times recently I've noticed I can't sleep well at night, and I think it's related to times I have wine in the evening in addition to coffee in the morning. It's like I drank a strong coffee at dinner time, except I didn't.
I was thinking that the liver processes many chemicals, and if it filtered caffeine out of my bloodstream but processed it slowly, then maybe there'd be some left at dinner. Then maybe all of it would be released in the evening back into the bloodstream because a more important toxin (alcohol) needed processing. And so then I'd experience the effects of drinking coffee at an odd time hours later.
Is this even possible? I.e. is it possible for:
- Caffeine to be stored in the body (in the liver?) after drinking it
- It to take a long time (6-12 hrs) for the caffeine to be processed
- For that caffeine to be released into the bloodstream and start having effects, with the release triggered by a glass or two of wine
