First of all, Hello Sherdog as this is my first post =)
Had my first cauli a week ago, and I've had problems with sufficient compression after the draining. Now I have a nice working, and not too annoying.
Since the cauli-blister was in the lower cavity of the ear i packed it full of stiff ear plugs (the type you use when you want to protect your hearing) placed a cartboard as a lid over the ear and sealed it shut.
This is my third day wearing it since the draining. Minimal refill when I checked today.
