Depression, rise in blood sugars, nausea, stomache, complete loss of appetite, gray foamy stools and being cold all the time. New doctor wasn't happy with my taking Inderol since I have diabetes, but it has worked well for 20 years and I have fairly good control on the blood sugars. The side effects hit me out of the blue, having been on beta blockers as long as I have Between being cold (It was 70 degrees out today) and the depression I don't even want to get out of bed. I didn't expect this. Still have a few of the Inderol, will call the doc tomorrow and switch back.
