I’ve asked this earlier with regards to my senior gal with CDD and sleeping disorders. We tried melatonin supplement 2hrs bed time but does not work. She is up at 130 am or 3am. Even after feeding her gabapetin (vet’s suggested option, tramadol doesn’t work on her) we had difficulty getting her back to sleep. She will doze off only till 5-6am when she is totally exhausted. She is on senilgine for the day. Any other possible combi?
