I have only swallowed on one person. Diet can effect the taste. What I did not like in the beginning was how warm it was. I really think it is psychological that you can feel it in your stomache because I felt the same way until I stopped paying attention to it. BEWARE OF FACIALS!! IF THERE IS AMPLE DRYING TIME IT IS DAMN NEAR IMPOSSIBLE TO WASH OUT!!! Take my word for it, don't try this at home! I forgot to mention that it is impossible to get out of you hair....sorry for any confusion!
