I was put on tramadol to help during physical therapy, and now while I wait for a new hip. Because it works as a serotonin uptake, it really did a number on me. So instead of weaning myself off I discarded them and put myself on 2 extra strength Tylenol and 800 Motrin. Which doesn't do much. I've been off them a week and have not slept more than 4 hours a night. I realize this is a side effect but I was wondering how long before it stops and I sleep again. I'm having a hip replacement in a week. Hope I can sleep.
