I used to drink a lot of Carrot Juice, but never mixed it or had an upset stomach. I'd usually have about 48 ounces, or more, at a 'sitting'. My reasoning was....it's a lot of effort so I might as well do it right. I've cut way back to about 24 ounces at a time. I've been including Green Smoothies in my diet, which are very filling. In fact, I'm going to have some Carrot Juice right now. I've been thinking about it for the last 2 hours. I buy carrots by the 25-lb. bag. I'm amazed how some carrots are sweeter than others. I have a good bag right now.....WY
