It doesn't last and it "hurts." That's the best I can do. I'm 56 tonight and have had too much to drink and I'll regret it tomorrow. It's that "experience" I remember; all the times I swore I wouldn't drink too much again, etc. They didn't really work but "time" did. I have weight and health problems and they hold me back now because of my drinking. I don't drink as much now as I use to because, finally, my body caught up to me. If your body is complaining, think of it and what it's telling you; WILL YOURSELF to listen.
