allergies
"This medication is incredible. It has changed my life. I use to sniffle and have a consistent stream of mucus flowing from my nose due to environmental allergies. This has completely changed how I feel. No more itchy red watery eyes, mucus, or overall discomfort. I can work without a tissue box nearby! If you have terrible allergies I do think it's worth a shot. Also I do advise you to take it in the evening as it might make you drowsy. The medication states it works for 24 hours but realistically it's about 18-20 hours."
