Can someone please explain the test you can do yourself to see if your breathing is in distress? I read about it here, but I'm still not sure I understand. Do you breathe in, then count when you are exhaling?

I missed my night time Mestinon dose, so I've gone ten hours without any. I felt like I had a reaction to my afternoon dose (so I was reluctant to take my night dose). After talking with a fellow board member (and friend), we realized that it was probably because I hadn't ate or drank much with the dose. I was feeling so anxious. Of course, that could have been a coincidence too as I've been under a lot of stress these past few days. Anyway, I'm having a little bit of trouble breathing. I did just take a Mestinon along with some food. So, hopefully that will help.

Thanks for any help.
