Hi and welcome,
SO how many did you take on an "average" day??? Have you been on opiates for a long time???
Are you determined to stop for good or stop until you can get more? As long as you take opiates you are prolonging the wd.
Length and severity of wd is usually tied to size of habit and length of use. Most people are through the worst of the physical stuff after 4 or 5 days. The no sleep is tough, take it when you can get it.
If you have any more questions, don't hesitate to ask, we're all here to help.
Hang in there it DOES get better,
bob
