I ate a can of cream of mushroom soup mixed with a little 1/2 & 1/2 and the rest water and 5 ritz crackers for supper and my B.S. really jumped, to over 200 from 168. I thought soup was O.k. the can said it only had 9gm of carbs. I'm not controlled yet though. 2 hours later it was back to 175. Any ideas?
