I have noticed now that I can't have much tonic water or 7 UP - even a single glass. The symptom I get is very noticeable diuretic effect. I would go to the toilet (urinate) as much as 5 times per night (small quantities) instead of normally once, occasionally never. I also get restless legs (drives my partner insane!!) This happens when I keep all other diet the same. Now that I know that I can tolerate a small dose of amines I find very dilute lime and soda much better for me. - longterm failsafe father
