Shellycat recently answered a post of someone who had trouble with the fasting because of hypoglycemia. I can't remember who it was now. But Shelly said they could eat sparingly up to 8 pm EP and drink the OO/GF at 11:00.Don't know if I remember that correctly so maybe you should check out her posts.
I personally have been taking Molo-cure A.M.P. It's concentrated aloe vera in pill form but is VERY expensive. 175 a bottle which lasts one month to begin with then it will last 3 months on maintenance. It has REALLY helped my hypo. Molo-cure states that Aloe juice liquid is too irratating to the lining of the digestive tract. Shelly would agree to the last statement.
I took the Aloe pills for diarreha. Don't think it helped a whole lot there.
