2cb tolerance and cross tolerance?

i thought 2cb was able to reupped/ redosed fairly effectively, unlike shrooms/ acid which is an immediate tolerance. i have seen a lot of ppl here say u can take it every ~2 hours and keep the trip going for a while, which i am pretty interested in trying, especially with shrooms. someone who i thoroughly trust on these matters informed me that it is still an immediate tolerance, so redosing after the first would be useless. i’m thinking i’m gonna try either way since i have a lot of 2cb and see how it goes, but does anyone have experience doing it more frequently with success? if i take shrooms as well will that block the 2cb? edit: + would y’all suggest taking them at the same time or taking one and then the other a bit later? i planned to take shrooms and then 2cb about an hour later and go up from there. please do not comment if ur telling me not to do this, they don’t mix as well as 2cb and lsd, etc. i am curious and i will learn my lesson if there is a lesson to be learned.
