i generally have bad problems with withdrawal for 4 days, sweats/chills the crawlies. then another 3 of restless leg syndrome. you're energy level might vary, i have never had much, one of the reasons i abuse narcs. one thing to do is not use again, this will simply prolong the agony. also i found it helpful to try and stay awake the whole day and keep a regiment. wake up at 7 AM drink a HUGE glass of orange juice and eat a breakfast a lunch and a dinner. i go to bed at 10 - 11 PM the 7 to 11 approach helps me sleep better, it ain't easy some nights though. i also take vitamins early in the day. don't be like me and do this to yourself over and over again.
