I've been of and off of meth for the last 15 yrs or so. It's a hard drug. Been in and out of treatment programs and you really have to have the mind set to get sober. I'm a little over a year sober now from meth, but am using marijuana now. Wish I could just live a "normal" life and not have that bad feeling in the back of my head. It never really goes away. It sucks, but you gotta try to keep yourself busy and away from that kind of situation. I no longer talk to the people I use to use meth with. My husband feels marijuana is the "lesser of 2 evils", but I don't agree. A drug is a drug and if your an addict, you know that. Life sucks! We have to take life as it comes and I guess I'm still in that point in my life that I'm still coping with how to deal with life, on life's terms. Good luck to you! Keep your head up and stay strong!
