Keep smoking! You'll get used to it eventually. And if you do it often enough for about a month, eventually you might have a hard time telling if you are high or not since you almost always are. It's usually then that alot of people get used to it. If you ever trip out, and you know you are tripping out, think to yourself: "I did this last time. I'm just trippin..." or "Fuck it, everyone in here knows I'm high already anyway. WhooHOO!!!"

The latter is pretty fun for me, but whatever suits you best.
