Agreed moderation is the name of the game. I usuall love to get stoned out of my mind, but at the same time, I'm not going to push myself like that and not expect things to get weird. If you like your previous experiences, but not this one, just smoke less next time. You don't have to get retarded everytime (of for that matter anytime). However, if its all or nothing, maybe it is time for a break. Keep in mind though, since you had trouble controlling your doses when smoking, that when eating weed its even harder, since you don't feel the affects immediately. Once you eat a certain amount you are kind of stuck with it. If you are content with you level of highness when smoking, you just put the bowl down.
