I have done 18 flushes and have tried mixing the ES in various juices - cranberry, orange juice, and orange/lemon. I found the ES just made the juice taste awful.
I just relented and bought an encapsulating machine and 500 empty capsules. You can get them from eBay but I got them from this very reputable website:
You can get lots of other high-quality items from this site.
There are many more healthy websites you can order this machine and empty capsules from. You don't even need the machine, you could just get empty capsules, scoop and put the capsules together. I just think this is more convenient.
Unfortunately, I wasn't able to get the OOO size machine or capsules, so I'll have to swallow more capsules - but I'm approaching automatic gag at the mere thought of ES.
