Might be the issue, might not but diet has a huge impact on sleep and energy. I know it seems kind of obvious but finding the foods that work right for your body and staying consistent with them will most likely fix your sleep patterns and general energy levels. Bowel movement timing and other aspects seem to be a good indicator of if my body is liking what im eating. I started a diet to help gain weight and was eating the same 3 meals every day and I was really surprised at how good I felt and how my quality of sleep was improving. Eventually I got bored of those meals and started to change things up but it had a negative effect on my energy. Its difficult to get right but once you do it is a game changer.
