Symbicort, flow of medication

[SJF89]

Took my usual dose of symbicort this evening and it felt a bit strange, almost like there was something preventing the air being sucked in properly from the device. Has anyone had this before? Is it to do with the mouthpiece being accidentally rotated at some point? I've never intentionally rotated it... Has anyone had this sensation before, and does it effect the drug getting into the lungs?

I accidentally rotated the mouthpiece on mine once, but it didn't seem to affect anything even though it says you shouldn't. I would have thought that if it was that important they would fix it in place.
