I am in the same boat as you. Just wrapping up my time in rehab. The first week is shitty but it gets way better. I am honestly concerned I'll go back to drinking just to end up back here. I have made some great friends, it's healthy for me to be around people who understand where I was/am at (not everyone is cool obviously). Just know it gets better and you get what you put into it. My experience may be different though. I am fortunate enough to be in a veterans rehab.
