DISCUSSION: What is going on? NAC causes burning brain and other

Actually the opposite happens. The burning sensation goes down, not up. A burning brain wasn't the only symptom. My anxiety and especially depression went way up.

Another benefit of bromine over chlorine is that it lasts longer. Bromine dissolves more slowly than chlorine, which means it can provide continuous sanitation for a longer time. This slower dissolution rate makes it an ideal sanitizer for people who travel frequently or those with busy schedules because it requires less frequent treatments.
