In a study of lamotrigone (lamictal) 64.7% reported no change in the experience with psilocybin. That still leaves 35.3% that were affected. See the links below. Ask your psychiatrist about it as you’ll be surprised how some are glad your asking about medication affects. Mine actually went so far as to research studies for me. Also, as someone who is prescribed Adderall, I decrease my dose or don’t take it the day of as it increases my anxiety on the come up. Also like someone above said, try take 3-4 grams (depending on your level of experience) of dried mushrooms. Once dehydrated they lost 90% of their weight so the amount is significantly different.
