Al is definitely experiencing withdrawal symptoms. He was down to the lowest dose of fentanyl - 25 mg, but he has been on pain medicine for a good 4 months. We were both tired and attempted to go to bed early last night. He couldn't stop tossing and turning and said his legs were so restless. He was also freezing. I gave him a benadryl since I read that it can help. I think it did because he finally fell asleep and is now sleeping in late. He is working 5 hours today and then 10 hours for the next 3 days. The withdrawal should be over in 3-5 days based on what I've read. I'll probably call the doctor this morning to see what they say. He wanted to get off the pain medicine before returning to work. Now we think that would have been better.
