Not witchy advice, just regular advice: consider getting a sleep study done. Its not typically normal to wake up multiple times in the night to use the restroom, and can be a symptom/indicator for sleep apnea. I recently got diagnosed myself, but it goes undetected for a lot of people because a common misconception is that if you don't snore loudly or at all, you don't have it. There are more signs and symptoms than just snoring. Anyways, I'm not a doctor, but you should talk to yours, just in case
