I get to re-experience the quitting sensation from chain smoking. Started vaping cut my cigarette consumption down by half at first, then in just a week or two I don't even want a cigarette. I could chain smoke 4-6 cigarettes in the morning, 2 cigarettes on each of my breaks, 3-4 cigarettes on my lunch break, 4 on the way home and another 7 or more at the end of the day. Also I would straight chain smoke for hours on the weekend. That's a ton of nicotine. Id wanna smoke before 2 o clock break. That feeling is just gone now. One 5ml tank of 3mg juice being only 15mg of nicotine, and the fact I can't even smoke that much juice on my break has completely limited my nicotine consumption to the point of switching entirely to the vape. It works. I remember last time having more energy too. The sweet liquid has also taken away my sugar cravings, but if I'm hungry it triggers my appetite. It helped I already had an awesome rig set up from the first time, but It works. I definitely prefer low mg sub on to those nic salt vapes, I think the nic salts are what made me relapse to smoking again last time because i was consuming way more concentrated nicotine.
