F2U, some pharmacies have an emergency number on their door. If you are a regular buyer with them, they might open their door and give you a few pills from your next prescription and not run it through their system until Monday when you get the full bottle of pills.
Just a thought. Or they might even be able to call another associated Pharmacy that will fill it for you.
Unless it is a chain store Pharmacy, then they are all closed on the weekend. Some have Saturday hours until a certain time. Maybe do some telephone calling.
Were you taking Lyrica on a regular basis or as needed..did you start it just recently? I have heard then some people do it that way.
Any Neurontin in the house? Perhaps your doctor will allow that drug to be used for a few days. I hope you find some answers.
Any friends or family who could lend you a few until Monday? I am just trying to think of some ways for you to get what you need. I wish you luck with this Friend.
