Perhaps you are smoking a strain that has some ruderalis genes in it. Four Way is one of those strains. It's 25% ruderalis, and ruderalis can give you a headache. but yes, you should take like a week off. I took a week off. In fact, I still am. I'm just waiting for my friend to call me up, so I can get some. I'm sure that later tonight I will be more blazed than I have been for awhile, because I have abstained from it for about a week. It sucks, I know. But there's no point in smoking if it isn't doing the trick, right?
