I went through a wheatgrass phase a few years ago after trying a few shots at a Whole Foods juice bar. Whew! Nasty tasting stuff, but the energy buzz you get from it is amazing. I decided that it was cheaper to start making my own wheatgrass juice and bought a stainless steel wheatgrass juicer (hand cranked) from some shop somewhere... can't even remember now! Then I also bought the wheatgrass seeds (wheat berries) from Whole Foods.. very cheap. Took a couple of weeks to grow, then I was on my way to juicing. I was so into it, I even tried (ha ha) a wheatgrass enema, which I had read about online. It was intense! My grow-your-own wheatgrass phase lasted about 2 growing cycles, then I gave up on it.
P.S. Never take it on an empty stomach first thing in the morning. You will pay the price!
