Try adding aloe vera. Just take off the skin and spine. I learned the hard way and did the entire leaf. Got the runs and nausea. Then my ND told me it was the leaf that did that to me. So now I leave it out even tho he told me to keep it. I just can't, too bitter and too strong for me :/
But if you only use the umm, clear "meat" from the leaf than you will be good to go.
Great job on changing your lifestyle. My ND told me to get a twin gear vegetable juicer. The one I currently have is the Jack one and it waste soooo much greens. The twin gear crushes it all. Check it out on you tube if you can. I can't return my Jack one other wise I would ge the twin gear in a heart beat.
Matter fact here is my juicing video
Not sure which link will work
