Just curious about this one, I get frequent migraines (see a neurologist, gp, etc all the time) and I get perscribed a whole cocktail of pain killers depending on which doc I'm seeing. Most of them contrain either codiene or OC - which I try to stay away from when possible. 9/10 times I'll use the codiene, sometimes these migraines can last weeks on end (yes its hell) and I end up using narcotics everyday for that period, but only at night so I'm not a total retard all day at work. I've posed this question to my gp and he said narcotics have an anti-catabolic effect so I assume by that they actualy help maintain the muscle I already have is that correct?

I always feel so weak after it wears off sometimes I can't help but wonder if I'm losing anything... I would switch to a non-narcotic pain killer if I was. Anyone know for sure what effect they have?
