Took 40mg a couple hours ago. Stomach did a little flip about an hour later, but it might've settled itself by now.
I feel tired--not like I'm about to fall asleep, but like I'm coming off a crash or something like that. Still here, but a little foggy.
I'll update this later to see how I feel towards the end of the day, but I felt like I should update after a couple hours of having taken it.
