Thermostat problems?

Is anyone having issues with their body temperature? I have a 30-45 minute digestion period after I eat, and during that time my body temp may range from insufferably hot to bone-chilling cold. It gets worse if I try to sit upright or actually do anything during that time period other than lay back at a 45 degree angle.

Since WLS my thermostat wars with the hubby have increased, does that count? Other than being colder than usual all the time, I haven't noticed anything different associated with whether or not I've just eaten. I'm sorry I couldn't be of more help, Karen 356/258/???
