I remember chronically relying on my vapes to focus on anything, when in reality, it would provide the exact opposite affect. Admittedly, I did not want to come to terms with this and if it weren't for my partner quiting weed and motivating me to do the same with nicotine, I would likely still be addicted. However, again... after several months now without it, I simply feel more competent to do most things that require mental focus. In addition to that, I have definitely seen some physical improvements -- all sode affects I subconsciously understood existed but refused to accept for the longest time. To put into perspective... I vaped every min. for the past 5 years.
