I have been on a fentanyl patch for 2 months. The first month, 12 mcg. The second, 25 mcg. Because of the heat and humidity, I have been forced to use the 25 mcg. patches for less than 72 hours. As such, I am short. I have one patch left an am seeing the dr. at the end of the month. What, if at all, should I expect by way of withdrawals?
