Caffeine is an interesting drug. It really affects people differently on an individual level, but also depending on what other things we may or may not be taking into our bodies.
There is a large thread on caffeine, which I’ll link you to. A lot of it is talking about quitting caffeine, but even if you have no intention of quitting, it would be great to have your experiences of how it affects you after getting sober in that thread if you ever feel the urge.
