IOP Going Up At Night

 Have had pressure pretty much under control for over 20 yrs with drops.

Lately the pressure has been up some in my only good eye.

Especially at night.  I will use the 3 drops... then if I wake up a few hours laters the IOP is up.

Any tips on keeping it down at night?

I have been sleeping with head elevated... but I tried it both ways and it does not seem to make much of a difference either way.
