LW-- kudos to you for posting your 'before' pictures, but for many people those would be very acceptable 'after' pictures. I know that it has taken me years to get to roughly the same state that you're in with my physique. You have a great foundation upon which to build.
I'd say best of luck with your rehab, but a successful rehab has more to do with effort than luck. So, best wishes for a successful rehab, and a clean and healthy life afterwards!
