allergies
"Love this medicine!!! I have year round allergies and I am allergic to everything; dust, cats, hamsters, everything outside, etc. I feel like I should live in a bubble. Nothing seemed to work. I've taken OTC drugs and prescribed drugs. All of them stunk. Allergy shots really work, but are too time consuming. Then I found Xyzal. Love it! Fair warning though, this drug does knock you out and the lasting effects carry into the next day, but I discovered that if you take it about an hour to two hours before your bedtime, you will feel fine the next day."
