Symlin Frustration!

This is day 20 of trying Symlin and I have only had two days where I didn't have a HUGE spike about 4 hours after eating. I use an Omnipod for my insulin and have tried extending my bolus 1 hour, 2 hours, no luck. I dive at 2hrs and then spike at 4. It's driving me nuts! My control was better before this stupid stuff but I REALLY want to lose some of the 25 lbs I have put on over last year or so.

I am only using Symlin with my evening meal and my Endo changed my ratio from 10 to 15 per unit for that meal. I am starting to think I need to change it back.

Any advice would be greatly appreciated.
