I take about 75 mcg when I want to fall asleep quickly and consider upward of .5mg quite a bit.
Where do you find such small doses? I think 5mg is pretty high, and I used to cut the pills in half, but recently I've been too lazy to cut them.
Gotcha. With too much I feel drugged rather than sleepy, and groggy the next day.

Not sure how easily transmittable the skill is, but I can easily break those into fourths by hand by placing thumb and pointer of each hand on one half and twisting one half slightly away from me and the other half toward me. Helps that those are a bit softer than others I've encountered
