Most of my friends had a problem with "yayo" and made it a point to do some "rails" before jamming(I would of joined them if I didnt think it would kill me)...they thought the session went great all the time,when we really never got anything done...I assume it makes you play good on your instrument,but it dosnt make a band as a whole get any where...and when it wears of there unable to eat,a 120lbs and constantly opening the car door to hurl,sniffing water to ease the burning holes and...do I need to say more?
If any of you are serious(which immensley doubt...and everyone should know this)
Its not worth it!
Try once,fail twice...
