I'm a recovering painkiller addict, (3-times over). Got on suboxone about two and a half months ago. Don't know if it shows up on drug tests. The only reason you would have to take at night after taking it that day, is because you didn't take enough earlier. If you take enough, will last for 24 hours. Yes, it takes care of all cravings. In my opinion, it makes you feel better than normal, a little extra energy.
Thank you, her son since taking the suboxone is very focused and is a different person. The doctor wants him to try 15 days and then if he needs another 15 days to let him know. I warned my friend that I have heard w/d can be bad. Hopefully he won't relapse, I don't know how well the sub works for cleaning your act up for good after you stop taking it.
