At 17 did a lot of acid, speed, pot, hash, and about everything that was out there till I was 19 then figured it wasn't worth it and stopped everything but drinking.
Stopped drinking before the first child came around at the age of 22 and didn't start drinking again till I was about 58 after having enough of trying to raise kids and all the old memories that were bad started to come up drinking started again and now I stopped smoking cigars and gonna start on not drinking and smoking cigarettes. One at a time just gotta get rid of old memories or at least let them lay on the side lines. lol
