I can't give you any advice on pills, but I can assure you from people I've known that you are not alone. My sister is an RNA and just got fired from her job for showing up under the influence from drinking straight gin the previous night. She went to work on her bicycle because her license was revoked for driving under the influence. Now she's facing jail time. They don't mess around in Colorado. She's going to have to ride her bike in the snow. Rocky Mountain High? Well, not really.
I had a housemate who was a maternity nurse. Every day she was dealing with the most emotional event in a woman's life: giving birth. She got addicted to Vicodin and couldn't even remember her own name.
So, believe me, you're not alone. Stick around here. You've found the right place.
