I've gone back and forth since getting sober. I'll do really good then slowly start adding more and more to my day. I would definitely say I can't do without it. I don't even have a year sober yet, so I guess I'm waiting until I get more sobriety from other substances before I remove caffeine and cigarettes. I guess you can be an addict with sugar too, but sugar isn't my vice. Caffeine definitely is. Thanks for the post - definitely made me think.
