I Have I.B.S., I Take BENTYL 20mg Tablets 4 Times

I have I.B.S., I take BENTYL 20mg tablets 4 times a day, I recently was "laid off" and had to apply for a low cost insurance, and while I wait, I no longer have a way to get my medication (unable to see doctor, due to no insurance coverage). My symptoms have returned in "full swing", I wanted to know where and how I could get a prescription for my meds while I wait for my insurance to become active? Thank you for your time
