Sorry you were disappointed K ...
Interesting what you say about a nutritionist. I actually did speak to one, quite a lot, in various separate appointments, on the NHS. I was referred from immunology - who ran a barrage of tests to see what I was allergic to and what was probably an issue of toleration. I got there via the digestive diseases clinic. All of this was via the NHS.
The whole kit and kaboodle helped me track down that I'm wildly intolerant to certain foods and these have a gut and psychological effect, that are (now were) exacerbated by hormones. I was told what to eat and avoid to alleviate symptoms, including digestive and emotional, and what to eat to promote well-being. All of this on the NHS. It's all worked.
