My fiance and I are having some friends visit from several states away. We haven't seen these guys in forever and we plan on taking a couple strips when they come. This will be the second time I have done acid and I want it to be better than the first time. A couple of different variables really hindered my trip. I got a pressure headache about halfway through and it caused a wave of negativity through the whole trip. It wasn't a terrible trip, but I would like some advice on ways to make the trip better and avoid things like headaches or buzzing head noises. Any advice or personal input is welcome!
