That is worth trying. I smoked for many years and found the combination of nicotine and caffeine very helpful when I was writing. It improved my concentration. I googled for information and got this https://www.medicalnewstoday.com/articles/nicotine-vs-caffeine#interaction. It says the combination does improve concentration.I have mentioned this before, and still doing more research, but there are several universities that are doing research on using the nootropic nicotine patches to help people with memory loss.
This is NOT nicotine from tobacco, this is plain nicotine, which is not addictive, helps with Parkinson’s and also with memory loss, so very different from any kind of tobacco use of any kind.
The price of nicotine patches is terrible but I think I want to give the patches a try. However, googling for information about the experiments got conflicting results. One site said nicotine does not help and another said it was proven to help. I think the best way for me to make a decision is to try it.
