help needed...

I found 2 bottles of pills, when I was looking around in the basement, in a box of stuff from my parents room, which they cleaned out like a month ago...any way I wanted to know if I can use them, and how many to take for a first time, I looked on erowid.org, but I can't find any info...the first bottle is like half full, and is says skelaxin 800mg, but it expired 2/28/04...is it still good, if it is how many should I take for a first time, and what are the effects like? oh and do you have to break them in half like oxycodone?

the other one is full, and says hydrocodone/acetaminophen 7.5/750 mg #40, how many should I take for a first time, and what are the effects like, the only other pills I have done are oxycodone, is the effects almost the same....

skelaxan is a muscle relaxant, they say one of the strongest ones howener for someone like me being tolerant to most meds youd want to start of easy, the hydro has 7.5 mgs and the rest is tylenol, i'd take a couple with the skelaxan then see how you feel, tylenol damages your liver but after taking them awhile you justlose the pain, so be careful
