Ditto on what IBKleen said.
Hi & Welcome,
It depends on the amount you are using, the length of time you have been using, your age, your general health, your metabolism, etc. Everyone is different with the length of time it takes to start to feel better, generally it is within 5 days.
Tapering is difficult for addicts and I would only suggest it if you have someone to hold them for you and dole them out according to a plan. Is that possible?
