It is possible for your potassium to be low.when I was in withdrawal I had some bad symptoms,ended up in E.R.my potassium and magnesium were low and a couple of docs have told me bananas and prunes aren't gonna help,they don't have enough..........I was also on sub at the time.anyway,thought this may be helpful.good luck,feel better
