Hi all

Maybe someone can help me out. Having been prescribed diazepam from my G.P a few years ago I stopped taking them when one box was empty. I yesterday found an unopened box with a date of expiry as 2024 and decided to take one. It seemed to have little effect so I took three more during the course of the day. I felt fine or as if nothing had happened at the time and went to bed. I then slept for 14 hours and have been groggy all day.
I am wondering if anyone is familiar with these diazepam at all please? They are a light blue round pill , blank on one side , on the other side is embossed DC with a score right across and underneath the score is embossed 10.

Thanks
