I hate tight waistbands, even "normal" ones feel tight to me. Elasticated waists just hurt so yes, drawstrings are best. I do have one very used pair of trousers that have a wide elasticated band around the back. They are perfect but sadly can now only be used for the garden. I got them from a charity shop so can't even buy more of that style. I thought at one point I had found something similar in a well known department store but sadly they didn't work out.
For sleep try Rescue Remedy's Night-time version. I use the drops. 5 on my tongue before I start reading my bedtime book. It works a treat. I was very cynical when a friend told me she used them but have had to admit that whether it's psychological, a placebo or they actually are effective I have been sleeping much better.
