Try to remember each hour that goes by is a bad hour you wont have to deal with again. What I mean is, the first days and weeks of quitting an addiction are the roughest. It gets better, slowly but surely so having been off them for a couple of days, you have the 2 roughest days behind you. I am happy to hear you're in the hospital, to me one of the best beneficial ways to help you stay clean in the beginning is a change of environment and staying away from other active users. I wasnt able to do this at first of course but another thing that was helpful for me was eventually when I was be fighting my brain against using again, if I could step back and in an unattached clinical way look at how my brain is trying to manipulate me into getting its addictive substance and then trying to find amusement in it. Its truly amazing how good it can be trying to convince you you need it when big picture, that isnt what you want.

Eventually your life will get better, you'll notice positives from quitting you werent even expecting. Mentally and physically. Im rooting for you!
