concerta and vicodin(need help!)

[thickasthieves]

I have searched through erowid and unfortunately could not find the answer. I have recently come into the possession of 4 36mg Concerta(methylphenidate) pills, and tommorrow i will be receiving 6-10 Vicodin(5:500). My girlfriend and I are planning on splitting them, 2 concerta and 3-5 vic each. I'm not really open to snorting either(concerta leaves gummy stuff up there and the vic is loaded with tylenol). What is the best way to achieve a nice high, without any danger, by mixing these two. I would much rather underdose but at the same time, I don't want to waste it. Any insight is appreciated.

p.s. If you could include the best way to prepare the concerta(i.e. how do remove the time release) that would really help

sorry for the multiple posts but i really need an answer as quick as possible
