Mixing Diphenhydramine (Benadryl) and Nitrous Oxide (nos)
Caution
Together they add disorientation and the risk of falling, which lasts well past the nitrous. Take less of each than usual, and do not use alone.
Additive dissociation and disorientation, with a raised risk of falling. Diphenhydramine's sedation makes the loss of coordination last well past the nitrous itself.
The risk here is to the experience — intensity, panic, thought loops, confusion. Physical harm is unlikely at ordinary doses. Setting, company and dose do most of the work.
