I get that. I make it up with more water to thin it out and minimize flavour then gulp it down and after have a small glass of water. OR try blending it with lots of ice as an ice cream, the coldness seems to make it more bearable.
Its awful but part and parcel of eating the same thing for weeks upon end. I think you'd get that normally with food. Try eating nothing but chicken for 6 weeks straight. I think we'd all be gagging after a few weeks lol.
