Don't do it man, trust me.
I thought it'd be ok, so I took some mushrooms and held 10 hbwr's crushed up in my mouth for ten minutes. I started feeling the effects of the mushies then I got the nausea from HBWR's. This made my trip seem like hell and I was vomiting everywhere and I thought I was literally vomiting up my heart and lungs and stuff and that I was going to die.
You wanna be in comfort on a trip.
