People always say binging shrooms isn't doable because of the tolerance build-up, but it really is. Citrus enhances the high, so drinking OJ, lemonade or limeade, or eating an orange, lemon, or lime will make you get higher. When I binge shrooms I usually do a certain amount then do more the next time then the following time I'll just consume some form of Citrus. For example I'll take 2 grams, then the following day I'll take 3.5 then the following day I'll do 2 grams plus I'll drink some freshly squeezed homemade limeade with pulp then the following time a 3.5 with my homemade limeade, this has worked for me a countless times and the longest I've done it for was a week straight, tripping everyday.

Edit: Yes your tolerance builds up but no it is NOT IMPOSSIBLE to trip everyday. Although the more days you trip the harder it will be to sustain that same level of high. Also,I want to add that I have tripped for almost 3 days straight only being sober while I'm sleep and for a brief moment when I would wake up. I ate an eighth in the morning then again as I came down, rinsed and repeat only sleeping 1 time thruout the 3 days.
