I fell once last year in the middle of the night as I went to use the bathroom. Although my head was bleeding, I suffered no concussion. So theis would not happen again, here is what I have changed:
1. Since there was a large space between the toilet bowl and the wall, I put a small stool in that space and covered it with towels so I have something to reach for if I lose my balance.
2. I roll up a towel and place it on the rim of the shower stall. My shoulder hit this rim when I went down, so now, if I fall in that direction again (my left side since that is weaker), it will cushion the fall.
3. Before I get out of bed, now I sit on the edge and gather my bearings instead of jumping out of the bed quickly which can cause me to get dizzy because of low blood pressure.
4. I actually open my eyes fully so I can see where I am going. Previously, when I got up in the middle of the night, I would keep my eyes half shut, thinking I would fall asleep again more quickly when I climbed back into bed..
