Same! I have ptsd, and honestly a terrible fear of the dark and its so hard to go to sleep at all.. but I do have advice, white noise, night lights, or cuddle companions (stuffed animals or pillows) help me a bit. And if that doesn't you should talk to your doctor about your sleep and how your adhd meds are not helping during sleepy times!

I use doctor teals melatonin essential oils spray on my pillow
