The first time it was smoking heroin and cocaine. Lasted about 2 months. I used to do it at work too because I was addicted. Shortly after getting fired, I smoked crystal meth to get through the heroin withdrawl. This is how scary heroin is, I was addicted after the second time I picked up. With the help of a marijuana dealer, I got clean after he cut off my heroin dealer. I'd call like crazy but he would no longer sell it.
I still remember laying on my bed on my 25th birthday, withdrawing from heroin, thinking how seriously I fucked up. It took a few months of feeling complete apathy until I began to improve. However, I still relied on tobacco and weed to get through the hard stuff.
Few more months later I found another job, higher paying and less stressful. However, I began drinking this time. Half a bottle of vodka everyday after work and smoking weed before and after work. I'd come over with a hangover everyday and I eventually couldn't keep this up for long.
Fast forward to now, I'm totally clean from any substance. I have absolutely zero fucking desire to repeat what has been a complete wreckage of my financial savings, losing my flat, and a waste of time.
What does worry me is the health effect it might have, especially the street drugs I took during this short period of time on top of the weed and alcohol. I'm alright now but I still can't wash myself of the guilt and the regret. However, it keeps me well away from it.
Looking on to the future, I am willing to be successful, and I realized that I can't do it with dependence on drugs and alcohol. I simply couldn't allow it to get in my way.
