lows,,, Byetta

Twice in the last week or so I have had Lows with Byetta. I do not take any

other meds to control blood sugars but Byetta. But in both cases, I took
my 
10mcg shot then ate something high sugar. ( I know, I know,,, generally
I'm 
very good)
But what I want to know, has anyone read where if you eat high carb WITH 
Byetta, you get a Hypo?
I took my Byetta, had roast beef and less than half a pototoe then about
30 
minutes later, had a scoop of raw cookie dough. (I know, I know). Then 
within an hour, I was down to 45 BS reading. Took a glass of orange juice,

slowing came back up within 20 minutes was at 70. I'm eating some nuts
right 
now for the fat and protein so I don't go too high too fast.

Anyway, this is the third time this has happend. Byetta, high carb=low 
sugar. Anyone else? or thoughts?
