Congrats on quitting for 3 years. You still have to be careful, I quit in 2002 and at 3 years sober I had to struggle for a while to maintain sobriety. I drank very hard for 10 years and the last year I needed vodka in the morning to make it till the liquor stores opened at 9am. I was drinking at least 2 fifths a day on the last year and barely ate and instead drank slim fast to get some kind of nutrients in me. Went to 4 rehabs till the last one took, my liver enzymes were very high and am very lucky that I check out fine now. I am writing this incase anyone is struggling now and thinks that they are too far gone...you aren't, you can still make it.
