excessive burping/constipation

I’m 31, male. Don’t drink alcohol, don’t drink any carbonated drink, don’t eat junk food. Don’t overeat.
Eat homemade spicy food, 1-2 cups of tea, ocassionaly, I’m constipated, sometimes, use alots of energy to release. don’t get much bowl movement unless I drink this herbal tea.
For at least last 2 months. I’m having problem with excessive burping. Average 1-2 burps every 12-15 mins in 12-14 hours minus sleeping. Beside burping after each meal, every time I drink a water(tap water) or even take a little sip of water, I get the urge to burp & sometimes it doesn’t come out eventhough, I feel like, its about to come out unless, I walk for few mins. Then it finally comes out. During burping, I don’t feel any burning. I’ve tried different ways to drink the water to minimize swallowing the air.
