I've just had my first Perrin Technique (lymph drainage, basically) session and the therapist (as does Perrin himself) strongly recommends the use of Vegepa, which is a DHA-free formula of Omega 3 & 6. Each tablet contains 560mg of EPA and 200mg of Evening Primrose Oil. I used to take supermarket Omega 3 & 6 capsules but then read something on the forums (I think) about it maybe not being a good idea for PWC. Vegepa is sold by the ME Association, I think, and in the past, I think research indicated that this stuff was good for us. Am I mistaken in thinking that there was some hint about us avoiding Omega 3 and/or 6? I think you are to take them in combination so as not to have an imbalance, so either one ruled out would be an issue.
