Something has helped clear my mind of fog

I've been suffering what we refer to as "brain fog for over a year. I had improvement with a short course of steroids 6 months ago but it was short lived. Someone recently gifted me NAC supplement with information+ I've been taking 600 mgs 2-3 times a day. This formulation is compounded with molybdenum +selenium. I noticed an improvement very quickly. I have clearer thinking, better short memory, improved executive functioning and higher tolerance for less than ideal sleep. I can concentrate very well now. And my overall mental processing is faster. I'm more verbal now. It's been a change that had endured for several weeks. I'm had no other changes in anything. Just this.
My experience is subjective and there's no way I can claim this supplement is the catalyst for improvement. It could have been an improvement just bc of time. My results don't *prove*- but since there are no side effects or contraindications that I know of, I'm continuing to take this, along with several other supplements.
I just wanted to pass this along. It's inexpensive and if people are just experimenting, this may be something to 'try.'
