Yes, drink a lot and also you can try Royal jelly. And less stress of course.

Also, make sure you're drinking enough water. That is very important and one breastfeeding moms tend to forget.

Mother's Milk Tea is a good booster. You can get it online or at the store, found with the coffee. I'll let you know now, it's nasty tasting. I mix it with orange juice. There is also lactation cookies you can order online or make your self. Try looking on Pinterest for recipes.
