I tend to find I'll have sweaty palms and feet almost the whole time on amps TBH. I really couldn't answer, never really found myself dripping with sweat in either case I guess, just very clammy.
For me the anxiety was usually worse during the comedown. Especially when I'm coming down and trying desperately not to redose.
But I have had a few times, with unusually large doses, where the peak was especially anxiety ridden and I would start feeling better somewhat on the comedown.
I usually found myself sweating the most starting during the peak and lasting through the first couple hours of the comedown then the sweating trails off for the remaining of the comedown.
On meth or pretty much other stims to unless I'm outside I don't sweat...my hands do though occasionally think just depends on dose and temperature around you
