I cant post in the wellness portion yet so I'll throw this here
I had always been a fitness junky, hated the fact that I smoked 1 pack/2 weeks not alot but yea I was still smoking. It did not really affect my performance much I run 5-10 miles easy and my lifting at the gym was unaffected even doing HIIT workouts.
Since I switched to vaping I started 24 mgs just because I did not believe it would satiate my occasional crave, but now I am down to 12 mgs. The nicotine delivery with my setup of various attys and pvs is insane NOW...I am very particular with my diet and everything else that goes with my fitness..
I noticed definitely that metabolism has kicked up into overdrive I lost 1 lb a week consistently for 3 weeks... to some this was a good thing, to me I was alarmed I had no idea what was causing this, I had to up my calories and even tone down the cardio...to counteract this.
Then I stopped vaping for a week I went back to normal. Can't stop vaping now lol so TLDR Had to readjust either the amout I vaped which was ALOT I love butterscotch eliquid too much I think hahaha. But ya my metabolism is up into overdrive. Alot of studies show that nicotine suppresses appetite but it does the exact opposite for me, after vaping I find myself hungry!! I went from eating 6 meals a day to like 8 smaller meals... I think its the flavors of the liquids that send a signal to my brain and stimulates my GI system... oh and I poop alot more now lol

Oh one more thing I spike all my liquids with liquid caffiene

esp before workouts... ahahaha
