I think they make a 1 mg pill? I’m doing the same as you though - cutting with a pill cutter and hoping for the best!

I’m two days past the Nucala injections and while I slept for the 24 hours after, my lungs feel good today so I’ll stick to the 2.5 for another week then I’m going to stop (per pulmonologist). If it doesn’t work I’ll be cutting up tiny pieces too.
