When I was 18, it was 18. When I was 19, I was 19. When it was 21, I was 20. My parents killed themselves when I was 18 and burned out house down. I lived in the garage got water from hose bib for 2 months, then they knocked the house down and lost water. They forced me out several times, but I had nowhere to go. Homeless shelter opens 12/1 until 3/31. Did that for two winters. I drank a lot, perhaps 1 liter every other dah of cheap vodka. Worked every night frkm 6pm until 2am cleaning entry carpet mats. Walked 4 miles each way to and frkm work at shelter. Slept in a 1973 Pinto the spring, summer and fall of 1983. Finally got section 8 voucher to rent $300 studio apartment for $90 in the spring of 1984. I was 20 going on 65 back then. I had a real reason to drink, not to feel the misery of my life. Misery much worse than most people will ever experience. I say if you deserve it, like I did, then yes. If you are still emotionally a child no. I haven't had a drink in 33 years now.
