Yes, keep coming here birddee, especially when you have cravings. It really does help to post and read, just knowing you have support from people who have similar struggles.
Thankfully I never got addicted to coke, though I do know about the comedown. Two days later I would practically be suicidal in my depression. Somehow I was able to realize it was the coke.
It sounds like it would be good to get to some meetings before you hit that fourth day craving and get some supports in place to help you get through that time clean so you can keep building clean days. You can do it!
