Hi BHTYH,
First of all, realize that you are in a better place then a lot of people here who are unable to go longer then a few weeks or a month without M.
Plus, You BH have no addiction to P! Dance in the street brother!
Now to your issue, what you need to understand is what happens when we are sexually excited, our brain creates feel good hormones called Serotonin, thats makes us excited and the heart pumps, it does a lot of things. Adrenaline is also released at a much greater level when we are excited about sex.
Now what happend is that your brain was used to feeling like this and it regulated everything accordingly, so your energy level and your sleep level and everything that comes along with it was regulated a certain way. Once you stopped, your brain and hormone level are confused and therefore you dont feel different.
Regarding the brain fog- It could be either that you are feeling depressed and therefore you are getting brain fog.
or that you are fighting urges too much and therefore your brain is exhausted, keep in ind that brain fog can also be caused by low energy levels.
Brain fog is an extremally hard thing to diagnose because there are so many different causes.
I am suffering from brain fog myself for a very long time sometimes it better and sometimes it harder. When i get aroused my whole brain fog goes away instantly.
I would suggest waiting a bot more and your brain will slowly get used to it. Meanwhile you must do exercise. When doing exercise your brain releases the same hormones and hopefully that will balance things out.
