4 grams of yellow, first get energy, after hour sleepy
A lot depends on the vendor. Some yellows are just mixes of reds and greens, so if that’s the case that doesn’t surprise me. If the vendor has yellow that is a result of the drying method (fermented white like mine), then energy is likely, and the sleepiness is likely because it was a bit strong and you had much of it.
