Euphoric Herbals?

K.
Have any of you ladies tried Euphoric Herbals to improve your milk supply? I exclusively pump and I normally can make about 1.5oz - 2oz per session, but my son needs at least 2.5oz per session so I am currently supplementing with formula. I have tried Fenugreek with small increase and now am trying Milk Machine from Euphoric Herbals. I also have Lush Leche to try as well. Has anyone else tried them with any success? I would love to have my supply increase enough to allow me to have even the smallest in reserve; I am literally pumping to feed and it's exhausting.
