As you know, I'm fairly new to all this.
I can never really tell when my ventolin is empty. My other inhaler has a counter on it, and when that is at zero it still feels like there is something in it.
Does that mean ventolin (or other inhaler without a counter) is less effective when it's nearly empty?
Sometimes it feels like it works less well, but that might just be in my head!
How do you know when you need a new one?
