Last pump best pump?

I cut down on the number of pump sessions in my day about 2 weeks ago from 4 to 3. But now I just get more in my last pump of the day and waiting to pump before bed is painful. I don’t want to try anything to reduce supply because I’m afraid of reducing it too much. Does it usually take this long to regulate supply?

I also looked into donating, and I’m kicking myself because I have had a drink maybe 4 times since my daughter was born. I waited four hours before pumping each time, and honestly I never actually finished each beer. But because I didn’t record the dates or wait six hours, I can’t donate any of what I hav in the freezer to my local bank. They give to NICUs so I totally understand. I’m annoyed with myself for not keeping track of that.

Has anyone used Human milk for Human babies before? Was it a good experience?
