After having tonsilitis, I used Listerine as mouthwash I thought it will help. The next day when I wake up,I started to feel something in my throat(difficulty to swallow)..I thought maybe it's phlegm coz its cold breeze in my place(valley)...so I didnt worry about that. After 2 days of using it I started to fell dry mouth and throat,and still didn't think about it coz I know its summer and that makes me thirsty and dry mouth, until I observe that everyday it really makes me feel worse coz I started to feel fatigue and severe dry mouth.. As in,I can't go outside coz after 5minutes of walking I feel tired and and really dry mouth. Til I started to get worry of myself and thinking what's happening to me,coz I'm not like this before. After 2weeks of suffering from all the changes and discomfort,I realize that everything started after I used the Listerine. And I started to search it from Google about the reviews from others,and some of my side effects,experienced by others too. I stop using Listerine last night and I'm hoping I will be OK after a few days.
Don't use Listerine....
