How do you pump to get more out of a session, to encourage letdown, etc?

Thought we could share our secrets! Maybe we'll learn a thing or two from each other!

***
I always chug a glass of water before hand.
Massage boobs before and during.
I watch videos of LO and look at pictures. I def notice that it takes letdown longer to happen if I don't watch a video. Often a difference of ~7mins vs ~10-15!
I always switch pumps mid session! ie I'll pull the pump off, massage my boobs, switch left pump to right boob and vice versa.
I'll often pull the flange off prior to letdown to get a better "latch".
I always hand express into the bottle at the end of each session
I'll move the pump in a circular motion
I always lean my body forward

What are some of your pumping techniques?
