Day 2…So far I have cold (expected), general wobblyness/shakes, puffy hands and ankles, constant headrushes (have to put my head between my knees whenever I stand up)..Anyone else in the same boat?

Hi Clairebear, sounds like a bit of either postural hypo-tension or even low blood sugar but if you are worried you should stop and check exactly what you have eaten and drunk compared to your recent habits. I cannot see how one day of reduced eating would cause such symptoms. Stay hydrated, and either go back to what you were doing or contact a health professional if this is the same again tomorrow. Surely, you would be expected to have dome something drastic to suffer in such a way on Day 2! Have you done so?

I agree that you should ensure you are drinking lots, which will help with your cold, too.
