Postural PVCS made worse when stomach is full?

[mickmick93]

As the title says, i have been dealing with pvcs that are triggered by posture, and it usually gets more frequent when my stomach is big and full from eating food or when I drink. It's gotten to the point where I often spend a lot of the day feeling thirsty, because drinking makes your stomach feel fuller faster than eating. I try to drink some water bottles every day, but I only take about 2 big sips every 15 minutes to avoid fullness. I've even lost some weight because of the lack of eating and drinking that i've had to do, because of this.

Does anyone know what the cause of this is? And what can I possibly due to be able to drink and eat freely again? My stomach also feels really tight and sore when i get full also.
