My name is Cheryl and i'm new to the forum. I was diagnosed with Type 1 when I was 40 years old. I'm on a medtronic insulin pump. I am frustrated by the weight gain since going on insulin. Since going on insulin I have gained 25 pounds and as i'm sure you can understand, its very frustrating and disheartening. My doctor has suggested starting me on Symilin and i'm wondering if anyone out there is familiar with this medication, and any possible side effects. From what I understand, it can cut down your insulin use by half. Thoughts and concerns???
