Personally I try to never drink anymore coffee after noon time. I could probably get away with a small cup in the afternoon but it's just not worth it. I hate it when I over do it and end up completely awake in bed. I've read some articles that say even people who can still sleep after drinking coffee late in the day are still messing with their sleep cycle. Apparently REM sleep gets delayed. So the overall quality of sleep is worse.

Everything is individual. Just know your limits and adjust. Feel like your body is not in the mood today at all? Skip it today. Simple as that, listen to your body.
