I took 5 egg yolks, 2 limes and added a lot of extra virgin olive oil to that (like a half glass).
I think it's the celery juice that produced the nasty side effects. It was way too much, didn't like the taste of it, but swallowed it anyway, cold as it was.
Maybe it helped in a way that I drank the juice though, since celery contains organic sodium, the celery juice is not taken up by the kidney's and excreted as urine, it rather travels along in the intestines, hydrating and helping excretion (but maybe also irritating a bit, since I lacked any appetite for food for a full day). Along with the fat from the eggs/oil, I think that's the combination which did the trick, since I've tried eggs with lemon alone and celery juice alone and it never worked as effectively as this time.
I'll keep doing the eggs/oil/lime combination in the mornings but not with the celery juice. I'll only add celery juice to the mix when I'm in strong need of a laxative effect.
