it seemed to help with my chest cold - although beware passing of gas near anyone nearby for the aroma may be an unpleasant experience for anyone, including yourself. And I know sometimes it doesn't bother you, in fact you may take pride in it, but this will be different.

n-acetylcysteine. Smells like the real deal if you break a capsule open. Same gastro effects if you mega dose it. I obviously didn't send it to a lab for testing but I feel certain it contains NAC. iykyk, pleiotropic benefits. Cheap, easy way to access it if you run out of a more expensive brand from some of the more "high end" supplement companies. Would recommend

I was told NAC supplements have shown promise in reducing cravings for alcohol use disorder while at a treatment facility. It's only my third day but I'm noticing an increase in energy levels and reduction in cravings. It's still early but initial results are promising. I'm also noticing a clearing "brain fog" which I'm hopeful will continue to improve. Very happy so far.
