Like "I have been taking Metformin for years. So far so good. Also have been taking Actos which has been linked to bladder cancer. Also so far so good. They both do a very good job to keep me in check w/diet. I will say that Metformin or Actos alone does not do the trick. You might want to Check whether you can take Actos plus Met. It probably will work best rather than Met alone. Actos is very expensive but you can get it free from the Manufacturer; if you qualify. You cannot have any health insurance and can only make much money annually."
