YES! most definitely! Your body is going through withdrawals. Usually that sensation in the legs, hence the name "kicking" You are actually "kicking" those opiates you have been taking. People that withdraw from heroin or methadone go through that, sometimes so severe that the legs just shoot out back and forth. It does go away with just some patience and prayer. I myself would not try to self-medicate because if I did I would just substitute one for another. Sorry you feel "weird", but just hang in there and it will soon subside. I have been clean for almost 3 years and I still get that from time to time. It comes from alcohol abuse for 27 years and other substances for me. I never did heroin, just everything. Good Luck!!
