we shouldn't think of "flashbacks" as some kind of condition
because this kind of thinking just leads to prohibition
(i mean...if that's your point, then go ahead, but don't expect kind words from me about the topic)
i agree with TheMMT, in that you shouldn't be looking at your life as sober vs. not-sober. You are always your conscious self, except your perceptions are affected in different ways by different things. Things don't leave permanent marks on your psyche (in the form of flashbacks, or a permanent changed state, or whatever) unless you let them (this can be good or bad).
If you ignore such things, they will probably go away.
The feeling of tripping is not something that you cannot accomplish while sober, it's just not very easy that way. Remember, all drugs simply mimic natural chemicals in the body, so it's probably possible to simulate a trip or whatnot just by raising levels of various neurotransmitters in your brain. I know I can make myself hallucinate at will...
If you're having body rushes or thoughts that scare you, I would recommend (in any time when this happens, tripping or not) just to take some deep breaths and try to keep attention where you need it. Body rushes warrant attention to the body and "mini trips" (dunno what you mean by that) warrant attention to the PRESENT instead of getting lost in your thoughts. Cause thoughts don't make happiness, actions do (well, thoughts can make you happy for a while, but then you need to act on them, or else you put yourself into delusion...i'm there half the time, lol)...I should try to take my own advice more seriously...heh...good luck, anyhow.
