Our ME/CFS bodies are very sensitive to such high doses, I think. (At least that is what I experienced when I tried the author's suggestions.)
Dr. David Gertson provides some information about his experiences with ME/CFS patients and amino acid imbalances here. He recommends relying on testing, customized amino mixes, and a doctor with ME/CFS experience for ongoing treatment.
think rather than trying supplements you could try to get your amino acids from quality food such as healthy proteins
It's also possible to get free-form amino acid supplements that contain most of the main aminos so that the body can utilize what it needs and won't be possibly thrown off balance by a high dose of a single amino. These can also be useful for anyone with digestion problems since free-form aminos don't require digestion.
Another reason for hunger might be blood sugar control problems. Many of us have hypoglycemia. I used to need food every 80 minutes throughout the day to keep my blood sugar up. (After taking liver and pancreas supplements for a few months I'm now up to 3 hours between meals.)
@HABS93 do notice the same hunger at night? Do you get light headed, have fuzzy thoughts, poor coordination or other low blood sugar symptoms if you don't eat after a couple of hours?
