Will 3 advil (ibuprofen) pms make me sleep?

It may : But u have to be sure about your liver functions, you certainly don't want to make that a habit, there are much better approaches and better medical alternatives for sleep than taking 3 advil (ibuprofen).

Learn relaxation : Skills (biofeedback may help -- www.Bcia.Org or www.Aapb.Org) & practice good sleep habits -- consistent bed & wake times, warm bed & cool room, quiet & dark room, minimize caffeine & alcohol, use relaxing pre-sleep routine, use bedroom only for sleep & sex (no tv, eating, reading, etc.). Talk to a sleep specialist or http://greeleypsychologist.Com/sleep.Xhtml for more details.
