I occasionally take Tramacet for headache pain when plain aspirin won't do the trick. I took 4 yesterday, 2 at 8:30 pm and 2 at 1:30 am. When my headache woke me up at 1:30 am, and again this morning, I felt like I was vibrating inside. My wife said I was twitching and shaking in my sleep.
Felt like a coffee overdose, but my hands were not visibly shaking.
Does anyone know if the pain killer could cause this?
