Take the Flexeril earlier - 8PM at latest. I got some good muscle relief from it, but that's fibromyalgia pain. I just can't take it with my tramadol. The combo gave me serotonin syndrome.
Tramadol works for my muscle pain too, but I was always late getting my second pill at noon, so I'm trying out the 100mg extended release. It works for about
12 hours, and I am getting away with 2 a day. Bad days I sneek in an extra 50mg instant release.
You can get sleepy with just Benadryl. It only lasts about
4 hours for me though. I prefer the smallest diazepam, but that's a muscle relaxer too and lasts only 4 hours. It's good in the middle of the night like now.
