When I was recovering from 7 fractures in my lower back, I had to go through withdrawals from Morphine. After two days of feeling like I had the worst flu ever and all the other F'd up things DTs make you do, it does feel like its going to last forever, finally, it was over and everything was great..
You will be proud of yourself knowing that you CAN and WILL survive. From that point on, life will only get better!
