    Not Worth It cautionary exp #118943

    Consumption: 3+1 pills on an empty stomach. Had 3 pills and 2 hours later took a 4th one. I quit doing drugs after a amazing LSA trip that changed the way I view many things in life, my relationship with my parents, my friendships, and the way I viewed drugs.
