nasal congestion
"I found Alavert to be extremely affective with two side effects and depending on how bad you feel they might not bother you. I noticed I had a ton of energy and couldn't go to sleep so I found myself cleaning. My house is better because of it. I also found myself getting up to pee almost every hour once I feel asleep. All in all it relieved my headache, dizziness and nasal congestion."
