For Type 2 Diabetes "I have been taking Janumet 50/1000 for about 6 months. My blood sugar has gone from 320 to around 120, which is a huge improvement for me. It really explains why I was feeling so tired and grumpy all the time! In the beginning, there was some diarrhea and stomach problems. But I noticed when I kept my carbs and sugar low, they went away. I know it can be extremely difficult to watch what you're eating, especially when living and eating with others in your household. But you need to do this for yourself. You deserve to live as long and as healthy as possible. My blurry vision cleared up. My constant weight gain went away, in fact, I have lost 15 pounds since using this. And I feel more energized. Very happy with this product."

For Type 2 Diabetes "Janumet/Januvia is toxic poison! Stomach pain, vomiting, diarrhea is pancreatitis caused by the poison pill! Janumet inflames your pancreas and causes your blood sugar to run high! All the aches and pains, stiff neck, headaches, and anything else happening to you is from the poison pill! If you are taking the poison and it’s working for you, be patient, you will have the horrible side effects soon! Merck should be shut down."

For Type 2 Diabetes "Have taken Janumet 50/1000 once a day for 13 years with no side effects. Then the doctor felt the dosage should be increased (my A1C is 7.8), so upped the dosage to 50/1000 twice a day. I am having intense heartburn, indigestion at night, watery diarrhea in the morning."

For Type 2 Diabetes "Just started taking Janumet 1000 mg yesterday. Luckily, my daughter, who studies medicine at university, read the instructions. I had a headache, which she said was low blood sugar. After I ate something, the headache disappeared. I have had severe diarrhea, though, both nights, OK in the morning???"
