3.5 grams of good shrooms should definitely leave an impression. lol
Visuals on a mild trip can be about nothing.
Visuals on a medium trip can be quite colorful and wavy. Walls breathing, things moving, stuff in the corner of your eye moving, slight confusion or medium confusion, over thinking things, feeling tough to walk and wobbly to walk, might be sweaty or cold or get hot/cold flashes. You should feel the fungus in your body making you shiver a bit at some point.
This is where I like to be when shrooming. Just above acid a notch.
Visuals on a heavy trip can be just as far out as DMT. Fractals, faces, melting things, you can get ego death or out of body experiences, you may "purge" and hate or enjoy it... you kind never know. If you did it with tea you might just go blind to a white light and laugh for 8 hours unable to comprehend the tv you are watching. Kinda unpredictable really what will happen in hefty doses like you are speaking of. Depends on ROA also.
Good shrooms you wont barf. I suppose maybe if you ate a ton of them.
But I think the ensuing trip would outweigh the negativity of the purge in your report. lol
I recently had some freakin' amazing shrooms and just two grams blew me away faces and ego death style when I usually munch a good eighth to see colors and walls breathing.
I had .65 of a gram the other day of the same shrooms for a pleasant body high, some mild confusion and some odd dreams. Then I got up at 2am and made a sandwich that tasted funny as hell, but shrooms always make me hungry. Then I came down playing Zelda ocarina of time.
Couldn't belive just .65 of those shrooms made a good threshold impression.
I should probably say you'll want sitters dropping a bomb with 3.5 g's of shroomies on your first time. You never know how strong they can be. I prefer to get a nice bag and test a little at a time. Even that two grams was way overkill for me the other day and I have done them a lot. Those ones were CRAZY potent. If you got the same ones I had or something for 3.5 grams on your first trip you'd probably go nuts without a sitter.
I totally started flippin out and didn't know what was going on. haha it's funny now but wasn't then. They felt like a truth serum and the truth was way too much to bare.
Those ones I could expect some visuals off just a gram. Nice body high too.
Just go easy on it. Get a large enough batch to start slowly.
Seems to be a reoccurring theme with psychedelics.
