How do I increase my milk production?

I have a 2 week old, I have low milk production, I am taking Fenugreek and blessed Thistle as recommended by the lactation consultant.I also make sure to feed her every 2-3 hours. I have heard from several people that it takes a little while for your body to regulate with the milk supply and not to give up, is this true? I also have no appetite and am force feeding myself, any advice on what to eat?
