My allergies, sinus congestion, and post-nasal drip (and the accompanying cough that can cause you to gag or wake up in the middle of the night) have improved immensely with taking 500mg of l-lysine twice daily on an empty stomach. I take it 30 min. Before breakfast and at bedtime. Huge improvement immediately! I have occasionally taken 1000mg dose as needed. I almost have no symptoms anymore!
I've tried several different brands, including generics, and they've all worked the same. I take year-round, as I have lots of trouble with dry heat in the winter and all kinds of pollen and dust.
