Wean off exclusive pumping

Whats the best way to wean off EP? I started weaning yesterday by just skipping one pumping session & only pumping when I got full, not every 3hours. But today I am in agony. I tried hand expressing (actually ended up hand expressing 2.5oz) but ut did not give me relief for long. When I do pump should I still be pumping to empty or just long enough to feel relief? I'm so ready to be done with this!! Lol
