Caffeine question!?

Caffeine is known to slow down healing. It doesn't do any damage to your body, so you're fine.

I've been off caffeine since I started my pre-op program in May 2016.

Haven't missed it. It's awesome to go to bed and be able to fall asleep easily, and then wake up in the morning refreshed... neither of which would ever happen when I used to drink caffeine.
