pill imo that's definitely part of the post depression. i still find myself on the computer anywhere from 4am-6am til my husband wakes up cause i can't sleep and don't know what to do with myself. i go to sleep early cause i feel like life is god damn boring without drugs! just because ones self is okay physically doesn't mean the mentality part of it goes away. i know for me that will be atleast a year. it's not even 'craving' for a drug, atleast in my opinion, it's just like 'what do i do now?'
you're on the right track with staying busy, classes & interviews etc.. try to keep staying busy. once you get thqat cabin fever girl it alllllll comes back i'm sure you know. i cannot BEAR sitting in the house i go crazy and want to go out and get the heaviest tranq i can find to just knock my ass out from the world of boredom and no drugs.
BUT, i know that's not really me thinking and jjust part of kickin' drugs. don't let em keep nabbing you, you're way further in the race and even just codeine can set back an ex opiate addict miles
