My daughter has been consuming 1 quart of Ketonex 2 every day since early childhood. She is accustomed to the taste. She has tried other products but cannot get herself to drink them. The thought of having to switch products raises her already high anxiety levels. She can hold on for awhile but the longer this situation goes on the higher her anxiety becomes. This affects her ability to function in school and at work. Anxiety also raises her leucine levels. She was almost hospitalized recently but has calmed down. What this is doing to her brain I can only imagine.
