You mentioned it turns out you have ADHD (turns out so do i) and that you began medication for that and it reads that this medication began at around the same time as you started on nicotine again.

I am inclined to ask the question. Do you think perhaps you are associating the effects of the ADHD treatment to nicotine use?

There certainly are some documented benefits to nicotine use. And much of what you say is verifiable. However, many of the benefits you describe can be associated with the treatment of ADHD aswell.

I accept i dont know your personal situation. I only read your comment and noticed the timing seemed to be a bit close.

On the subject of vaping, i personally experienced some sticky phlegm and trouble coughing this up as well as issues with lung capacity and the dependance on the nicotine made me extremely irritable and unable to concentrate until i vaped.

Also it takes longer than a few months to break a nicotine addiction. I still uphold the idea that there may have been some withdrawal going on there.

However i am happy to conceed the point if you genuinely disagree. As i said i have no idea about your personal situation.
