I may have to give up the protein shakes or at least try another brand. Initially I was having one after each gym session and that's been for 6-7 weeks or so now. Although recently I've developed a slightly nausious feeling about 2 hours after I have one. I'm almost certain it's the shakes as I only ever get it after I've had one. Has anyone ever experienced this? Bleedin' sodds law I've got about three half full tubs left! I might have a go at selling it in the classifieds, can't remember if that's allowed though.
