Why does it take my body so much longer to feel the effects of medicine/ so much longer to wear off?

I don't know whether or not this is off topic, but I think what I'm discovering is that it takes l my body much longer than most people to feel the effects of drugs, and much longer to wear off. For instance, if I take a medication that's supposed to work in 15 minutes, it always will take me 30 minutes to feel any of the effects. I noticed this a long time ago with alcohol as well. For most people a high dose of Prednisone usually shows some effect in most people pretty quickly. For me, it took four full weeks to see any effects whatsoever.

And it will take much, MUCH longer for the effects of any drugs to wear off. Most people feel sober an hour or two after having a drink or two. For me, it takes three hours at least, sometimes more.

This really, REALLY sucks for someone with UC who is trying to determine the effectiveness of medications, which sometimes take weeks and weeks to take affect in the first place....

I know it's not UC related, but can anybody shed some light on why this may be?

Hmm interesting, so how quickly an IV drug affects me would determine if it's absorption versus metabolism? Would that apply to general anesthesia? I've only had general anesthesia twice before, but in both cases they've had to ask me "Do you feel anything yet?" once before adjusting the knob and putting me out.

What about injections like local anesthesia? I've always required a ton more novocane than most people for dental procedures. It too takes longer to take affect and a ridiculously long time to wear off.
