I was chain-vaping the 18mg all the time, and I didn't want to be doing that, so I figured I would try the 24mg. Well, I did try some 24mg this morning, and I was fine at first, but now I have a slight buzz. Before I got that slight buzz, I placed an order with Steve where everything was in 24mg. So, I'm unsure if my body is just adjusting, or if I need to quick get ahold of Steve and ask him to give me everything in 18mg instead.
