I am not predisposed to any sort of addiction (except sugar, I suppose), so it is so interesting to be around people who are addicted to things. Caffeine is the most common around these parts. I have friends who are comically addicted to caffeine. My wife is addicted to caffeine. When she needs it she will immediately stop whatever she's doing to go to the nearest dispensary and get her fix.
She's tried to quit a few times (she's trying right now, in fact), and it's hell for her. She really struggles with it.
I think it's all funny, but maybe I should try and be a little more sympathetic. I clearly have no idea what she and others are going through.
