The first night on Lexapro I woke up to find myself rooting through my husbands underwear drawer...then again an hour later looking for something in the linen closet...don't know what. The second night I got up, sat in the lounger and ate an entire tube of Oreo's at three in the morning.
So...yes...these drugs can cause this behavior! Plus very weird dreams, at least for me!
Do you have any history of sleep walking. I am sure it is a quirk and I too think you should talk with your physician. It could have been an interaction with the meds.
I understand your concern. (((((((((Hugs)))))))))
