Not really but they will hit you a little harder and faster on an empty stomach but might make you naucious. Just eat a light breakfast and then pop em. I love me some benzos but those are what got me in rehab so I stay far away from them now.
I think it would be very interesting to read On The Road during the depths of a Benny Binge. You should try it out for me!
I always take them on an empty stomach. I've never had any problems with nausea when it comes to benzos, but everybody's different. For me it seems like if I take them on a full stomach I don't feel it nearly as much, and if I eat a lot while high on them it seems like it wears off quite a bit. Could be all in my head though.
