Diphenhydramine HCI for insomnia

Is this safe to take in a daily one time dose of 25 or 50mg to help with insomnia on it's own with no other medication?

I'm reading about really awful withdrawal symptoms on various websites and forums though most seem to be taking triple digit doses in mg. I don't intend to go over 50mg daily if I do decide to take it. If I get diminishing results on this dose, I'll just taper off it and then stop completely.

I've also just started looking into sleep aids based on "doxylamine succinate". Any advice on whether to take Diphenhydramine HCI or Doxylamine Succinate would be appreciated. Tweet
