trying to make a pseudo speedball

[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
