asthma
"I had vernal keratoconjunctivitis (VKC) and recovering from it was a very painful experience for me. I was 10 at that time and I wasn't affected much. I had asthma before, montelukast helped me to beat asthma without nebulization and inhalers. With increase in asthma attacks, the intake of montelukast increased. I started to get anxiety, nightmares about various things and my VKC experience haunted me, tremors occured and my chess skills went down. I hate that drug and discontinued it. The increase in dosage ruined me."
