fussing

My daughter is a month old and for the past week or so she cries from 9:30/10-12:30/1 at night. She'll fall asleep for 10 minutes at a time then is up crying again. She wakes up again between 2&3 as well. We've tried gripe water, burping her, laying her on her tummy, bicycling her legs.. she is on medication prescribed by the dr for reflux.. I'm not sure what else to try but we get up at 5am for my husband to go to work and this is really taking a toll on us. Any advice? :/
