Not so much with alcohol, but when I was prescribed Ambien to help me sleep there were a couple of times I made some questionable purchases.
I never knew this, but at least for me, if for whatever reason I don't fall asleep after taking Ambien, all of a sudden everything seems like a good idea! And it turns out that this is a terrible time to open up the laptop and go on Amazon. I ordered a whole series of books thinking to myself, "Wow, if I read all these books it would make my life so much better!"
The books arrived later that week, and I didn't even remember ordering them. After some time I figured out what happened. The books are sitting on my self, unread.
Amazon and Ambien don't mix!
