Start at 5mg - reviews of papervar say its strong as hell, i.e. "overdosed" - so see how you respond as far as acne, oily skin, etc. You should "feel" something (or see sides) w/in a couple of days.
I was having orgasms just by having my clit touched..I have NEVER been that sensitive. It was amazing..I would take var just for that effect, truth be told BUT, unforunately, it went away afterwards. ;(
