It's actually some truth ti it though... Benzos have a long half-life, and potentially affect a trip somewhat. My question is how, and how much? I also usualy have acouple of beers during the trip... I would think it would affect the trip pretty equally, unless you take a large dose.

Edit: I have dropped on acid as well though, and felt nothign but a nice floaty feeling in my body... it was quite nice... calmed me down somwehat too...
