Frequent urination at night

I thought I had a UTI, but tested negative.

The only symptom I had was frequent urination. No pain, no cramping, just peeing a lot!

The thing is, it only happens at night when I’m laying in bed...

I drink a lot of water, but don’t really pee that much throughout the day. But as soon as I lay down to go to bed, I immediately have to pee. A few minutes later I have to go again... I usually end up going about 3 or 4 times in the last hour before bed.

I stop drinking water an hour or two before I go to bed, but I still have to pee multiple times before I can fall asleep!

I started taking a probiotic before bed and it has helped a little...

Anyone know why I’m experiencing frequent urination only at night?
