Hi Pro... Our friend and SR member Raider just went to rehab, and posted a similar question. The link below is to the page I posted a long list on (on my mobile so I can't cut and paste the copy). My post on that page has a long list of all the stuff I really found useful.
Good luck to you! Rehab is hard, but it's also incredibly worthwhile and helpful. You are so very lucky to be going!
