I tried the nic nac. I used then 3 times and I wasn't feeling anything much. Didn't really help me stay more focused. The fourth time it got me feeling very sick. Haven't tried again since.
I've heard of that brand. I tried a zyn few months back and it was a 3 milligram one and it absolutely floored my ass. Definitely had to sit down on the couch for a little while.
