I would try the Benadryl and see if it works, but if you take it, it's not a good idea to smoke or drink after if it doesn't work for you...
But I have taken it (starting with 1 tablet, going up to 2 if needed) when I have been agitated in the past, and it has helped me calm down, but not sleep, but that's just me. It hasn't helped me this time around tho because I've been manic vs. hypo.
It helps my husband fall asleep tho.

It's never a good idea to self-medicate, even tho I do. Honestly, the pot is better than alcohol. I don't know how many drinks you are having, but be careful

It's Sunday, so I guess that means you can contact your pdoc tomorrow, and I think you should. I think I remember you saying you don't take anything for your anxiety, which you seem to really suffer with. Maybe it's time to think about doing that
