I don't know that much about all the drugs you've mentioned, but what I do know is what exactly is normal these days??? If you have reached the point where the pitfalls of addiction far outweigh the "boredom" of sobriety, you are probably in the right frame of kind to truly quit. I didn't realize for the longest time that my need for "fixes" whatever they might be was a sign of something deeper malfunctioning within myself. No amount of drug or high risk behavior is going to fill that hole. You've got to fill that hole one day at a time. Make your life worth living.
Thats what I'm doing. I've only had a pharmaceutical problem for a little over 3 months, but looking back I can follow the yellow brick road that got me here. Thankfully due to my horrid past behaviors I quickly realized what deep crap I was getting myself into. Hopefully, I've caught this early enough that the consequences will be mild.
Welcome back. I hope you find freedom from the prison addiction can be.
