Hey, how did you know. If the grass was good, I would actually hallucinate on the stuff. Started serious use of substances in junior high school all the way through first two years of college. I took a long hard two years to completely kick all my substance abuse habits, and during rehab I saw people who breezed through it and others that were crushed. When someone tells me caffeine is too much for them or that withdrawal from it is a disaster, I tend to believe them.
