The doctor prescribed to her some sleeping pills but they didn't work.
Why did the doctor prescribe her sleeping pills?
Her regular drugs were not effective and she didn't want to visit the doctor again.
That sounds frustrating. If you're given medication that doesn't work then you should contact your doctor for a follow up. If you don't get the proper treatment then your condition won't ever improve.
Dude I will do it after the weekend.
That sounds like a good plan. Set a reminder if you need to.
