A little known secret about hydro, when you work out when you are on it you don't feel the pain. You can make insane gains if you can deal with the occasional loopiness or dizzyness. Do a set of crunches to test it if you won't injure what you just had worked on. If you do feel any pain at all it will be very dull, allowing you to do many more reps than usual.
A good little hint for getting some use out of being loopy and numb. I had bad burns once and took 30 hyrdocodone pills in 40 hours, and the day I got them I had been shot up with morphine about 5 times, which did nothing for the local pain, just my demeanor. Before the 3rd double shot, my mind only repeated 1 word for about 30 minutes. Destroy! Then I finally calmed down and started to try and deal with the pain and they gave me another big dose and it felt like I got stomped on my chest.
Hydro is my favorite narcotic. It's nice on the stomach, smooth and overall very effective with few negative sides. Working out on it is a huge bonus. I suggest abs because you are already laying down and you can keep going no matter how lightheaded you feel without feeling the local pain of burning the muscle out or losing control/balance and hitting something.
