Be careful. Yes it will increase your relaxation, but it will also destroy your memory and increase the possibility of doing something stupid while totally blacked out.
Best case scenario, you'll just fall asleep, and wake up in the morning wondering where all your pills went. Worst case scenario, you'll do something extremely regrettable. For example, I have a friend who took a large amount, did something pretty reckless and stupid, and then when he "came to" was arrested and had to sit in prison for a YEAR. This kid was 20. I also know people who have died from combining large amounts of benzos with opiates + other CNS depressants. All of this, for a "high" that you wont be able to remember?
Trying to get "high" from benzos is a dead-end road, you reach a point where all that happens is that you fall asleep and don't remember anything. It's also a good way to slowly become addicted to these insidious bastards. So I guess whatever you do, be careful.
