Hang in there BubonicPlague and good on you for addressing your addiction. It's a rotten old thing, addiction, I know.

It often takes a bit of time before you start feeling more comfortable about not using your drug of choice and just being in your own skin. Have you considered going to NA meetings? Or perhaps there are Caffeine Anonymous meetings near you? I'm not sure if such a thing as 'CA' exists but whatever - 12 meetings, being around supportive people on the journey of change & recovery outside of the support house, may help to quite some degree because I've been there too, friend.

Just keep going, keep going, keep going! Good things await you!
