Suggestions to increase lactation?

Savannah

I started taking an herbal supplement called fenugreek (as suggested by my midwife) to increase my milk supply. It worked amazing! I was originally pumping 1/2 an ounce total per session after feeding from both breasts to 3 ounces within a matter of days. Unfortunately I have to stop taking it because it has made my LO miserable with gas. Any suggestions on how I can get more out of pumping sessions without supplements?
