"So for constipation, 10 stars! It worked fast too but if you are not taking your pain pills, do not take! I thought I'd be ok with the fentanyl patch in my system as I had not needed one of my oxycodone that day and I had horrible side effects of withdrawal symptoms, fever, chills, couldn't get warm then would sweat real bad it was terrible. I thought I had an infection again because those side effects mimic infection too. Today I really want to take one but am scared, should I take it BEFORE I take my pain pills? What works best? I'm already constipated, don't need to be feeling sick also! Thanks!"
