Otherwise, you lose the magic. I have a general rule for drugs (alcohol included) and it's to have them spaced out. Ideally, it should be a "few times per year" type of deal, if not less.

I always shake my head at "habitual coffee drinkers."

If you're a heavy coffee drinker, try abstaining from it for at least a couple of months, your first sip after that long duration will feel like you're on shrooms.
