I don't know if this is related to taking Montelukast at all, but I've found recently that I seem to be getting stressed and anxious about things a lot quicker than I used to. It doesn't have to be anything big, either. I have a lot going on at the moment, primarily to do with running an after school club and having disagreements with the other leaders, but I am finding I'm not coping with it as well as I used to - I'm becoming more snappy and frustrated with them, and it's starting to get to all of us.
It doesn't help my asthma in that stress seems to be a trigger- I'm getting stressed, so I'm getting wheezy, then I get anxious and stressed about the asthma..
No idea if it's related to anything, but I have heard that it could be to do with montelukast and I felt I needed to talk about it somewhere.
Sorry to rant, and also if it is not relevant to anything!
