shogun, you are being ripped off (unless that price is in yen). Shop around. Mine is 100g for about £8. NAC has not affected my visuals at all, just cured my anxiety and sense of ungroundedness (sort of agrophobic vertigo), and made me clear headed. It may be a specific sort of anxiety it helps with and perhaps youll still need benzos etc for the rest, but for me it has been all ive needed to cure anxiety. I have said previously to have a big dose now and again then a maintenance dose of about 600mg or a single 1ml scoop of powder per day. I am going to go back on that. I have started taking a 1ml scoop (about 800mg) 3 times a day with meals, plus more with alcohol. This level also brings a relief to my leg fatigue and gives a general feeling of physical strength.
