May I suggest spacing out your trips a bit more as JG has already mentioned. Its a tough road to go down when your outlet for fun is drugs, no matter what they be. Now that's not to say tripping isn't fun, it's an amazingly 'fun' experience in my book, but I don't jive with the "I've got nothing much to do today/this week.... I'll eat some of this" perspective, if only because its gotten me into bad places in the past. Got an event coming up? A friend you haven't seen in a while who will soon be around? Going for a hiking/camping/climbing expedition? Have some questions about a behavior or relationship? Inspired by a physics problem? Amazed to find a certain flower blooming by your door? Those things and many more I think are all appropriate stims for a trip. But I don't think boredom is. Surely you work, or are chasing knowledge of something in some way -- dedicate yourself to that, and to your family and friends, day in and day out. That is your weekly fun. Go for a run. Climb a rock. Hold someone close who needs it. And then when a little prompt occurs -- add a psychedelic to the mix.
Not trying to tell you what to do or how to enjoy your experiences. This is just my advice. Be careful brother, take the road for the road, and remember, something brighter and better is just around every corner, and under every stone. Be you sober, or in hypserspace.
