Insomnia has been a big issue for me. It's the main reason I need medication. I went too long with too little sleep and I got so depressed. Seroquel and Klonipin along with an SSRI is my cocktail. Seroquel was the med that finally knocked me out.

Some watch outs are diet related. What you eat and drink will affect how you sleep. I do better with a low carb high protein diet. Alcohol also messes with my sleep. Exercise will help as well. Meditation also was helpful for me.
I hope you get some good ZZZZZ
