I have noticed that I get hungry after taking alfalfa tablets (3 a day morning, noon and night).
But also you might want to consider taking ginger extract (which is good for nausea and stomach upset) and it will stimulate your digestionhttp://www.naturesway.com/?pid=13100
Also fennel is good for digestionhttp://www.naturesway.com/?pid=12700
If you take them on an empty stomach (about 20 mins before you want to eat) they could help your appetite. I like natures way. They are quality products
