Shrooms do for me when I eat too many straight and dry. I still do it anyways lol I find it adds to intensity, but does acid have the same comeup effects? Or is it always a smoooooth trip?
It can definitely have anxiety on the comeup, I guess some may experience nausea but that may be more of a psychosomatic reaction. Its not as 'heavy' as shrooms that's for sure, but you can get clammy hands, chills and fairly anxious.
On occasion during the come-up, I get a moderate feeling of flying (and believe that I am), but it usually fades away after a few minutes. I suppose that if you are prone to motion sickness, you could get queasy if things start to move about on you. I have never experienced that though, so its just conjecture on my part.
Lol. I think this may just be you man. But yes, you can experience nausea. I find it to be a mental thing like Guerillabedlam said. If you don't think you're nauseous, you're not nauseous. It's all about what you think you're feeling. From my experience, I've only ever seen one person who thought they were going to get "sick" from acid. This person thought they were vomiting into the toilet. Really they were just sitting over it dry heaving and spitting into it. It's only as real as your mind makes it.
You can definitely have anxiety on the comeup. I've only been nauseous when I had something else that wasn't sitting well in my stomach. Never if I haven't eaten in a couple of hours. Personally, having some anxiety when it starts hitting is a good sign for me that I've taken the right dose. Usually by an hour later I'm not even thinking about it anymore.
I do on particularly good trips..but I kinda enjoy the tension..makes my head feel like a tornado or something...and at any second everything's gonna pop outta the top : )
