No, but I think I know what's going on. Within a few minutes or maybe an hour or so, I just go back to normal. I think that's how most people are. If you've took acid a good amount like I have, this is probably psychological. You somehow have formed the connection between sex and that distinctive day after acid feeling. The thing is psychologically, you can bring back the day after acid feeling sort of at will if you've tripped a lot. I'm speaking from experience, once you've tripped a number of times, sometimes you can psych yourself into vaguely psychedelic feelings when sober.
