If you keep the potion down for 30 minutes like you did then the potion has done its job perfectly. Reasons why you were sick are complicated and range from a possible reaction to the citrus to something in the olive (It is very important for some people to have excellent quality olive oil). Other possibilities are that the stones and unseen waste expelled form the liver and gallbladder was not acceptable to the intestines.
The maintenance parasite cleanse right before the flush may have been a step to far as the walnut hull tincture is a mild poison and a cholagogue (increases bile flow).
Everything you did like getting up is OK as I said before the potion works its magic in 20 minutes.
Of yes, well done on an excellent cleaning programme.
