Despite my love for SR, I personally avoid using the word sober. I'm often not emotionally or mentally sober. I ingest caffeine and nicotine, and now I'm on prescribed psychoactive medication. I take in food that changes my brain chemistry, and I let myself get tired and hungry, which does so as well. I'll never be a truly sober person -- I just strive for sanity and peace, and I strive to remain abstinent from alcohol because I know I can't have either when I use.
