Unisom and b6 hunger

I’ve been taking Unisom and b6 on and off for a few weeks now and every time I take it, no matter the dose, I wake up starving and I feel hungover. My dreams even revolve around food until they force me to wake up. After I’m awake, I struggle for the next few hours trying to catch back up til I feel normal again. I’m 100% sure it’s the Unisom and I won’t be taking that anymore. I know this happens to some people with Benadryl and other antihistamines but I need to know that I’m not the only one who gets this from Unisom. Lol.
