greenfrog,

You need to relax and let your brain heal. When you feel this sense of imminent symptoms, it is likely your body saying to take some time off and rest.

You are over-analyzing this. You are very early in to recovery.

What ever research your naturopath is referring to about melatonin does not show up in online searches. Melatonin is used to help with sleep to facilitate healing. It is not a magic drug for sleep. For some it works but for others it just causes a short nap then waking up with a struggle to get back to sleep.

Sleep for a PCS subject requires good sleep hygiene. That means developing a routine that settles the body down prior to going to bed. Proper food intake and a lessening of stimulus starts many hours before bed. You need to find what works for you. Everybody is different.

Hope this helps.

My best to you.
