I find it makes me feel generally a bit drowsy and sometimes feel a bit sweaty, but as I take numerous other tablets at the same time, I can't be sure it's the MUPS. I make sure I eat before taking it, but before I had this I did have gastro-refux problems and would often be sick immediately after a meal or a glass of water. Never noticed a difference personally re: blood glucose levels, but as I'm able to keep my food down consistently, this will ensure I'm not losing vital fluids and dehydrating. I did require a bowel resection, due to a pancreatic blood clot and lost 2 mtrs of dead bowel nad have to take warfarin now and have bi-weekly blood tests to ensure my blood viscosity/coagulation/clotting levels are within range.
Good luck in finding an answer, I'd be interested to find out too.
Mart.
