Hi Karen,
thanks for these ideas - I'm compiling anything that may apply, in case the doctor's solution doesn't work.
Being me, a food diary would be an excellent thought - but the trouble is, now that I'm not head cook and bottle washer for Jan, it makes keeping track of her diet more of a challenge.
In the past I kept such diaries at home, and that included the amounts of things eaten as well [I have always kept records of almost anything since early youth].
Thanks for your post; I really appreciate it.
