Walking my dog when my legs gave a hint of getting weak and weaker, I felt a bit dizzy, and shaky.. I felt this before about an year ago aswell. On this occaision I even felt nausea and dry heaved thrice and a 'wet' heave sort of, once.. I wlaked a half mile to an office..sitting down helped. I'm type 2 diabetes, metformin, pioglitozones, and some others, not related.. Nausea still hanging in - even some scattered 'pains' about the abdomen and cardiac 'protests too..
