So here is what's going on: I decided to go to the gym and run errands before sampling the brownie (for obvious reasons). I got back and showered and ate 1/2 brownie at 6pm on a relatively empty stomach.

Background:
1/4 of good buds in brownie batch
baked in 8 in x 8 in pan, then cut into 16 pieces
I ate 1/2 brownie so I have 15 1/2 pieces left
The Math shows that each brownie contains 0.44 gram, so I ingested approx. 0.22 gram

Personally, I prefer to gauge the effectiveness of the treat on an empty stomach b/c my system is much more responsive in this manner. In other words I know what situation I will get myself into if I have one after watching football and drinking beer all day, or if I eat a bowl of cereal early in the morning and then want a brownie a couple of hours later.

So right now I am feeling a little heady, craving a little more high - NOTE: This is the point where a lot of newbies screw up and munch down another one. Resist the urge! If you are 2-3 hours in and the effects havn't accelerated to the point where you are really, really buzzed THEN go ahead and have another 1/2 piece.

I'll check in about 8pm to give another update.
