hey Tingles,
I know it has been a few years since you put this post up, but I am so glad that you decided to post what you did. I had a similar experience when I also decided to extract dmt from MHB using the naphtha method. I took it a few times, and felt a little ( because I only did a little), but on the fourth time, I "broke through" and had a spectacular and horrifying experience of God, myself, and the meaning of life. it was a wake up call for me to change the path I was on. it was terrible. for weeks afterward I had nightmares, then started to get strange spots on my skin, lost weight, couldn't sleep, couldn't eat, got an ulcer, then four months laster I developed burning and tingling sensations all over my body along with muscle jerks, and joint pain. at one point it even felt like I had a lump in my throat when I swallowed. I eventually went to a doctor and tested for many things, but they found nothing. he put me on vitamin B shots and tablets, magnesium tablets, and eventually put me on zolatil antidepressant. they all helped a lot, but the tingling still remained until just recently. the only thing that changed in my life recently is that I took neem extract for three weeks straight twice a day and I also decided to act on what was shown to me during my dmt experience. I began to repent to people around me for the wrong I had done to them, I changed my heart attitude and I confessed things that I thought I would never confess and it really has helped me. I cannot pinpoint exactly what it was, but I do think that all of what I just wrote synergistically worked to cleanse and beef up my body and cleanse my soul. dmt is powerful. I too researched it and didn't find anything out there about bad trips until after it was too late, but in the midst of my dark shadow of the night experience, which lasted almost a year, I learned a lot about myself and have been able to use that experience to change and be redeemed by the grace of God. the spiritual veil is there because our bodies cannot physically handle much of what lies on the other side. it is not hidden from us in order to control us, but to protect us. I hope and pray that your health gets better soon. thanks again for your post.
