Diazepam Abuse

Hello everyone,
I've known Diazepam for a while, it's a kind of tranquilizer. Diazepam did help me sleep, help me dream less and less and reduce my heaches.
But recently, I have had a few problems. Sometimes I don't remember what to say, forget where i left my wallet, and some other memory problems. Diazepam might have caused that? Should I go see a doctor?
maybe, are you seeing a dr for the perscription?
If so, talk to the dr about decreasing. or decrease yourself. idk anything about it. but if it is a sleeping medication, it is putting your brain to sleep. probably too much in your system built up over long period. decrease. btw - I am not a md.
