NO PROBLEM! I HAD TO STOP IT COLD TURKEY (NOT BY CHOICE). The first 3-4 days I couldnt tell I'd stopped...it stays it your system a LONG time! Then on the 4-5th day I started feeling w/d's. Nothing like hydrocodone...but still no picnic..Thank goodness my doctor refilled my meds that day..I have no idea how much worse it would have gotten or how long it lasts. I think a slow taper is the way to go...just my 2 cents!-Hope
