I recently posted in another thread about this.
I haven't been regular with NAC because I have to order it from abroad.
I have been taking NAC now for a few months, around 2400 mg daily divided into 1200 doses. Two in the morning thirty minutes after breakfast and two at night after dinner.
What do I feel?
I feel awesome, energetic, my brain fog clears up, major sinus drainage (sinus that was previously giving me a blocked nose is now flowing and I can breathe better). I am glowing and best of all, I can sleep 10 thousand times better. I sleep and wake up early. I sleep uninterrupted for 6-10 hours everyday and if I do wake up to go to the bathroom or someone wakes me up (Grrr...) I can go back to sleep like nothing happened. I get just enough sleep, and I wake up at proper times.
My bowel movements are more frequent which I guess is a good thing? It means stuff is moving out instead of me being constipated?
Do I get any side effects like herxing and diarrhea?
Only if I take more than 2400 mg, I'll get loose bowel movements and stomach pains or abdominal pains or if I pair it with Vitamin C. Nac alone with water works wonders.
I hear you must take zinc and copper with NAC as it gets rid of heavy metal but for some reason that gives me diarrhea....
