I have started taking medicines and now I have peed in my sleep. I take gabapentin 1200 mg 3 times day , metformin 500 mg x2 at bedtime (less stomach issues), fluoxetine 60 mg in morning, meloxicam 15mg in morning and low dose 81 mg aspirin in morning. When i was just taking metformin it didn t happen only after I started the other meds. I am 52 and I don t even realize I have to go to the bathroom until I wake up to wet bed.
