Karin,
I am so sorry to read about your ailments! Good luck with the new paints you have discovered.
I decided to start using oils again after a 20 year hiatus because of the water soluble oils. I have 2 children and didn't want to expose them to turpentine etc. I am very happy with them. I do notice that when I go to an art class with people using traditional oils and turp, I get a slight headache. The paints you have found sound even better as you don't really need a mixing medium and if you do, it is non-toxic.
Hope you feel better!
