Yeah sounds like me. No matter what I am 2a by bedtime. However if I really pump it up in the a.m. And let it BONE DRY after 90% diffusing and DON'T touch after SOTC (must be BONE DRY before SOTC) it'll last pretty well.

Key points:

Diffuse
Then let BONE DRY before SOTC
Do not fuss or play with it after SOTC
