When Im at my home in Texas and I dip, I get a very small buzz, just enough to relax me. Right now Im visiting my parents up north who live at a high altittude of 8000 ft. I just put in a dip, the same amount I usually do and I got such a huge buzz that I almost fell over. I dont know if the higher alttitude is what caused it or not. Has anyone ever had this happen?
