1. Are you on HCG from your naturopath? Many ppl on Rx take a break every week to avoid becoming immunized to it. Perhaps two days rather than 3 seem adequate to switch over from HCG. If this is where you got the HCG, maybe that is their experience.
2. Splurge means no sugar, no starch. Once you are clean from those, any indulgence can make you feel like crap. On the other hand in a healthy body, meat and fat can be a treat.
3. Surgery requires protein for recovery. Do not try to limit that in the process. You mentioned "spleen". What kind of surgery? Is it elective at all and is it possibly diet-related?
