What do you think is more likely to create excessive thirst in response to the supplement Evening Primrose OIl)? The thirst was not accompanied by excessive urination, and my body is now puffy, i.e. has edema. * Sensitivity/Allergy to Herb itself * Herx reaction * Reaction to change of ratio of fatty acids in body (Evening Primrose has a high amount of GLA--an Omega 6) In addition, I had extreme headache, slight fever, diarrhea and high sensitivity to noise. This lasted for one day after taking the supplement (fading away for the most part by the second day). I've had the other symptoms as part of a herx, but the thirst in particular perplexes me. Guesses?
