i did 5meo-dmt on some 1p and hated it... would never take shrooms on acid with what i've experienced from drugs... i know 5meo-dmt and shrooms are a bit different. honestly i tolerate shrooms more, but there are things about the body high i don't like on both and i get kind of the same vibe. done shrooms a ton of times and threshold to mild average doses of the 5meo-dmt like 5 times... 5meo-dmt and acid was awful for me, like nausea fever experience while i was moving on a magic carpet through all these paintings or some shit. that was the only time i've ever felt like i was moving that wasn't an ego loss type trip from psychedelics. it was kind of like the spins from alcohol except moving foward. the visuals were cool, but it was sickening. i had a come down after the trip too and i don't normally experience that. i get some nausea on shrooms wouldn't want that on lsd. maybe the OP is getting some enjoyment out of peaking on the shrooms to get over the nausea and then taking the acid though. hmm... or they don't really get shroom nausea like i do... i tolerated shrooms for years just to trip. after having steady acid connects, i lost my interest in dealing with shrooms though... i don't really even trip anymore cause the HPPD i have from weed though (which i like). i might start taking shrooms to play guitar in the future cause it makes the injury in my back feel stronger when playing guitar which kind of bothers it, but that's about all i can see them being good for. prob only take a half 1/8th or whatever. have to get really occupied with doing something with the trip or i get focused on the nausea.
i'm not saying people shouldn't try these combos, but kinda yuck to me... lsd and analogues are my fav alone compared to shrooms or other psychedelics i've tried. i like to say like 80-150ugs... everyone has their own thing though.
