Long story short I was on the max does of Gabapentin and tramadol for years, while taking percocet as needed when it got really bad. I cut my dose down signifincantly a few years ago. However, over the last four months I have worked my way totally off of them both, but still taking the Percocet. After about 8 hours after taking the percocet, my body gets really jittery and restless and I can't stay still, I just have to keep moving. This keeps me awake at night most of the time unless I take a percocet right before bed. What i'm experiencing used to happen with my tramadol but it has been out of my system for three weeks, so i guess its the percocet. Will this eventually stop and if so how long will it take?
