Has anyone heard of agitation or crabbiness as a side effect? A ...

Yes I have been on Singulair for about 6 months. It controlled my asthma and allergies beautifully—BUT—it finally dawned on me 3 days ago that I was constantly overly-irritated and set off at the slightest things, I was constantly agitated, impatient, angry angry ANGRY and temperamental. A total b*tch most of the time. I thought it was just because I am overworked and raising a toddler, which leaves me tired and worn out. I just figured that was how I'd become because of my busy lifestyle, as I get older. But I've never had a temper, and the rage I often felt and had to fight hard to suppress scared me, especially when having to exhibit self-control around my toddler. I found myself very short with him, impatient, almost mean. That is SO not me. My husband walked on eggshells around me. I don't know how I came to my senses, I think coming across some websites like this, I just had an intuition to look into seeing if these were possible side effects of Singulair, and lo and behold, I find HUNDREDS of people experiencing the same thing. I feel month by month it was building in me more, leaving me more and more short tempered and angry and less and less like my old self. I've been off of it 3 days and ALREADY my husband has noticed a difference. I feel calmer, more patient, nicer, and the anger and irritability has definitely reduced. I know as time goes on, I will hopefully go back to my old self. I only hope there are no long-lasting effects! Now my worry is, how to control my asthma?!?! LIke I said, it worked beautifully on me, except making me a mean, impatient, irritated crab .NOT worth it! I want the old me back and am going to get myself back to where I was....Good luck!
