I have been gluten-free since 5/21/2012. I have suffered insomnia since my teenage years. After being gluten-free for a couple of months I started to sleep better, but for the last two months I am back to only sleepin 4-5 hours a night. I also have a lack of energy and weakness. The other day I tried to change the setting on my shower and was not able to twist the shower head like I had been able to before. Anyone else with these problems?
