Thanks for all the replies everyone - they have been really useful in helping me decide to go ahead and try it.

I probably should have rephrased the original post slightly as I don't expect it to fully physically heal me, but if it can give me some insight or understanding of what it going on then that will be an improvment of sorts and help me move forward.

What I ultimately feel like I need to do is get outside of my body and get some perspective on things. From what I have read about DMT breakthroughs it sounds like this will enable me to do just that.

I remember about 5 years ago when I was only a couple of years into this illness, I had a very strange experience while laying in bed one night. I had been smoking some cannabis and went to bed in a fairly relaxed state. I was laying on my back and noticed a throbbing sensation in the forefinger of my left hand. This throbbing feeling grew stronger and started to move up my arm - then I began to notice the same feeling in my other arm. This sensation continued down to me legs and up to my neck. It felt like a lead blanket was moving up my body and although my eyes were closed I felt like I was about to seperate from my body and float up to the ceiling and through the roof! However I was prevented from seperating completely by the pain and tension in my head, sinus and neck areas. It was almost as if I had a load of helium ballons tied to my feet trying to lift me up and a heavy weight on my head holding me down. This feeling continued for about 30 mins before eventually I needed to get up and use the toilet.

Since that day I have since learnt that this is classic sleep paralysis as experienced in lucid dreaming while using the WILD technique. However I have never been able to repeat that experience since that night 5 years ago. The pain and tension in my head which was stopping me from seperating has since extended down into my chest, arms, torso and even my legs. This is the physical illness that I am trying to break free from and why I think (hope) that a DMT voyage will help me to finally break free and maybe even become better.

I hope this explains my intentions further and thanks once again to everyone who took the time to read this thread and reply.
