Tripping is about the trip and so is life, its a journey and you have 1 vehicle. It doesn`t have to be laced with chemicals to be a worthwhile experience. So much to do, so much to see and so much to understand. Chemicals can only provide so much of a trip, you have to make the rest yourself. How many fractals do you have to see and how many times do you have to feel "one" with the universe?
I think taking a break for a while for you will be an amazing experience, doesn`t have to be for long either. Tolerance will drop, your mind will soak up some of the world and re adjust, your body will be happy and ultimately you can have a crazy trip for less on that. See what life has to offer, while you can
You can always return back to your "Fear and loathing"
All the best buddy!
