Im starting to think that besides food allergies my dark circles could be a cause of nasal congestion which is also linked to dark circles. Reason being? I SNORE really really really badly to the point that its embarrasing. Just last weekend i spent a night at my boyfriend house and man did he tell me about my snoring...lol. (blush) He said I snore realy bad and so did other people that witness me snoring in my life time. im interested in a neti pot which i heard its an alternate to an air purification. which one is better? and any results?
