It wasn't a negative experience...I'd say it was quite profound. But I personally would not take any "psychedelic" substance again, mushrooms or other, because I believe it can open doors you may not be able to close again.
I know they can be very helpful for some people in dealing with addictions as in your case. I'm just not interested in using them for recreational or any other personal reasons.
DMT is very interesting though, because it is produced naturally in our bodies and is probably associated with dream states. The experiments done with it by Strassman are fascinating.
DMT saved my life and soul, not only by curing my addiction but by introducing me to god. I'm not a Christian but I am very spritual and full of faith, I know I was somewhere before I was born and I will be somewhere else once I'm gone from this life and where that is depends on how I live this life. I can relate to Christians and I believe we worship the same god just with different approaches, Jesus and the bible just isn't the path to god that's meant for me. I find god in nature, and in the souls of the people I care about. I can even find god in the bowl of a pipe if I smoke it quiet enough, I can find him in a canoe trip down a creek or river, I can find him on a long walk, and through meditation. If I were to pretend to find god in the bible it wouldn't be real and god doesn't want that for me. I call my belief system "spritual shamanism" and it works for me.
I would never use DMT as a toy or a recreational drug but there is a place for it in my life, maybe once a year or every couple years or something I don't need it right now I'm still riding high from the last time. I am a fan of psychedelics though but only in small amounts, I like a light trip on mushrooms and the occaisional LSD adventure, although I steer away from LSD because 12+ hours is a long friggin time. psychedelics are actually the only drugs I would ever consider doing because they're non addictive and at the core of my soul I'm an addict. I've had a hard life, grew up in poverty, raised by alcoholics, and I fell into that generational curse for most of my life, I fell in with bad crowds at a young age. started smoking and drinking when I was barely even 10 years old, I have doors that I don't want to open but sometimes I need to open them to better understand myself and to deal with things that I've buried and repressed. I truly believe without psychedelics I would be dead or on my way to death. I certainly wouldn't be the man I am today and wouldn't have been able to be the father my son needs. It's medicine if you treat is as such. I always go into a trip with intention and that's always helped me to stay grounded and to turn it into a positive experience.
But I agree you shouldn't even consider them if you don't need them and if you feel scared or anxious thinking about them, then they are not for you.
