Isn't 100mg a really high dosage? If you just want creativity, I would suggest much lower dosages. There's some 5mg honey candies you can buy, so you could try taking one an hour and noting down how you feel about an hour later. If you forget time, how many you had, or what you were supposed to note down, you've probably taken too many :).
For me, between 5-10mg gives me a nice little background buzz but doesn't make me lazy. For higher dosages, unless I'm already doing something active (hiking, coding, out with friends etc), I usually don't have much motivation other than to melt.
Edit: Etain forte lozenges are the honey candies I was thinking of.
