Bi-est cream vs Divigel

HRT has helped tremendously, but I still have occasional lingering sleep issues, such as hard time falling asleep or waking up earlier that I would like (ie 3am/4am). Just has a session with a NP at MIDI and am going to try Divigel. Has anyone here made such a switch? What should I look at for? I am going from Bi-est 80/20 to a starter dose of Divigel .75 a pack.
