i don't have the answers regding how long they stay in your system. I just wanted to remind you to drink lots of water...gatorade will also be good..gotta stay hydrated. At the bottom of this page on right hand side are health pages...see Thomas's recipe, and amino acid protocol..there are natural supplements..advice on helping your w/d symptoms. Depending on how much, how long you were using..everyone is different..you got 48 hrs...that's good. As I've heard here from a wise person. "You have to be okay with not being okay for awhile." Yogi Relaxing Mind Tea..healthfood store.
I hope you stay clean for you first..then you don't have to worry about external things ..like job etc..
It depends on how much drug is in your system. If you go cold turkey good luck you will go through terrible withdrawals. They could last a while go to the family doctor tell him you are a addict he will help you if you let him, make sure he or she is not a tic tac doctor.
