Can't sleep.....any suggestions?

So I'm I a little more than 2 weeks out of surgery and have not gotten a good night sleep since then. I am a side sleeper but have not sleep normally, flat in my bed yet. When I lay flat or on my side the liquid in my bag moves toward the stoma and wafer which is what caused it to leak before. Also if I lay flat, the stool just stays put rather than move down the bag. Anyone have any advice on the best way to sleep? I've been on the couch propped up by pillows. Also does anyone know about drain care? I have been keeping a bandaid on the site but it is kind of tender and sore over there. How should I take care of the site?

I always (mostly) slept on my left side. I would sometimes also rotate my bag a bit around the snap on part (I wore a hollister two piece) so that things would definitely run down towards the bottom of the bag instead of staying completely horizontal and risk filling up over the stoma/wafer site. It was really hard for me to get comfortable flat on my back after surgery and even as the months went on I was always at least semi propped towards one side either with pillows or blankets.

As for the drain site it should heal pretty quickly. I remember one of my drain sites healed without me even realizing it, the other took about 3 weeks before it scabbed up and then kept coming off/rescabbing over the next few weeks. As long as it's not oozing, or red or hot to the touch it should be fine. I kept a bandaid on mine just for peace of mind but the doctors all told me it wasn't really necessary after the first few days.
