Three weeks ago Thursday I was proscribed 10 mg oxycodone hcl for a surgical procedure. I took the two pills four times a day the first week then two pills once to twice a day until last Friday. Since Saturday I have been experiencing awful conditions like sogginess, stomach pains, diarrhea, body aches, restlessness, extreme exhaustion, irritability. Am I going through withdrawals? If so, how long will this last? Today I no longer have the mental grogginess (that was gone yesterday) but still have the exhaustion and diarrhea. Last nights sleep was terrible with body aches and pains and restlessness. Please help. I am at my wits end.
