Anyone Experience Sweating While Eating?

Lately [the last couple of months] I've noticed that part way through a meal like at lunchtime I start to feel warm and then begin to sweat, mainly around the head and neck. It may last 5-10 minutes before stopping. It doesn't give any advance signals like hypoglycemia does. I don't experience any feelings. I have had many bouts of hypoglycemia and it's nowhere near the same feelings. I don't feel any different after the sweating stops. Not sure that this is the best group, but anyways has anyone else been through something like this. I did switch from taking Losartan to taking Telmisartan for BP control, but not sure how that could be the cause as I take it at bedtime.
Plus this afternoon 07/30/2026, 3-4 hours postprandial I started to get an uninitiated episode of hypoglycemia. I really didn't do any serious activity to bring it on. All I had for lunch was plain oatmeal with whole lactose-free milk. I didn't nip it in the bud, but did catch it early enough. Normally if I wait say 3 hours after eating and then go shopping, the walking around the store is enough to bring it on and I can almost make it happen at will. If I shop right after I eat it usually doesn't happen. I'm not sure if I overproduce insulin or when I do need it there isn't enough blood sugar to counter it.

By uninitiated I mean not enough physical activity/exercise to cause my body to need to metabolize glucose for energy so it just sort of happens and it's sorta rare. Almost idiopathic in a way. I guess it was cream of wheat not oatmeal, but I frequently alternate between them. If I wait several hours after eating to do any walking, etc. I'm almost guaranteed to have a hypoglycemic attack. If I sense it coming on I slam down about 20 grams of glucose.
