I'm following a plan from my dietician, the meal replacements are ones that she's formulated, I no longer take my multi-vitamins i case of overdosing on certain ones whilst I'm on there shakes. I drink loads of water, I'm not convinced its my diet, I feel fine normally, not starving, no headaches etc, until I had this one episode of dizziness/feeling faint and now I'm drained! My dr said it was just a feeling faint nothing else... Not overly happy with that diagnosis, it feels like more than that from my end
