>>1133623If breathing overall is not possible without them you might as well go the full way and use cyanacrylate aka super glue to fix one into its position permanently. A tiny drop on each surface spread out a bit combined with the pressure should do the trick. Less is more in this case since you just want a thin film establishing the connection, use too much and the film will harden unevenly which makes it less strong.
Cyanacrylate once hardened is skin neutral and non-toxic, it's even used in first aid wound-spray to control bleeding, spray on there, close wound manually, edges stick together, wound closed, bleeding stopped for now.
This of course means that you will then have one of those things permanently on your nose (or at least until lard and sweat from under there over time reduced the connection of the surface to the skin so far that it again snaps away.
If you just want to apply them at night that is a problem, you need an adhesive that for one is strong enough to hold it at its position the entire night but weak enough that with a firm rip connetion can actually still broken. Also the stroger the glue the more it will damage the skin when finally removing them.
Still, with its strength but at the same time non-hazardness my vote would still go to experimenting with cyanacrylate, maybe find a teeny tiny amount to apply to one each evening that fixes them to the nose strongly enough but at the same time has not enough contact surface to withstand the pull. Start with the smallest amount you can manage to squeeze out though, that thing is strong stuff - small drop on finger tip, press two fingers together, and you cannot pull them apart anymore.
