let us chug pill bottles

[atomic1fire]

just have holding more than one pill equal a fistful so it creates a fun mental image when you stuff fistfuls of pills into your hungry craw

Alternatively clicking and dragging from the bottle to yourself with harm intent could let you eat the bottle's contents.

So for example you could find a random cabinet, eat ALL the pain killers, and then go on a rampage before whatever horrible after effects set in.

edit: With the possibility of coughing up multiple pills.
