Yes its been a while now. Off and on during the time I've been away from the forum, I've felt that sort of doomed feeling, here and there. When it happens, I feel very vulnerable. Vulnerable in the extreme, you might say. But, I think I'm starting to overcome it. I think that you guys were right, its the ego not wanting to submit. That's really the only thing I can come up with. I haven't felt it in a while now, and I think maybe I'm actually becoming stronger for it. Its never going to be a good feeling, but I think that its something that I need to gain mastery over. If I can master it, then future trips, should have a harder time "harming" me.
My friend calls it your "psychic constitution". Maybe I just needed more of that. I am not sure. I felt it last time, about a week ago. Even when it was more frequent, it still wasn't all the time. It would be maybe once per week. When I felt it a week ago, it came in response to me thinking about undergoing another heavy trip like that. Only this time instead of 3.5g, I was going to bump it up to 6 or 7g. So that I could see what others see, and perhaps have a trip something like Terrence Mckenna would talk about. And do it in silent darkness. But this time, have a close friend at the house.
All I wanted when my trip was over, and the Doom feeling first reared its ugly head, was to have another human being around. Just somebody. Anybody. So this time, I'll have that already on hand. Also, as some have suggested, a little mary jane. That is supposed to go a long way towards helping with this type of thing.
