Dosing Advice Needed

Rookie here. I have some chocolate bars that I like. Ate one gram's worth for a concert and it was perfect for the experience. Soon, I will be going to concerts three nights in a row, and I want to replicate the same buzz level all three nights. I will have had a break before the first one, so assume no tolerance.

I assume the way to do this is to increase the dose each night.

If I take 1g on night 1, what would people recommend on nights 2 and 3?
