There are all sorts of med options for dealing with the paranoia and the euphoria, but nobody can help you if they do not know what is going on. Personally, I learned the hard way that I just had to always lay it all out for him or her (Pdoc). If that meant I wound up in the dang hospital, well, then, so be it. Better than getting worse. Or worse.

So, my counsel is basically the same as the wise BirdDancer. Tell them what is happening as best you can and let them help you sort it out.

Of course. I do not know your story at all, but the only thing somewhat related to your late afternoon/early evening symptom stuff is sundowning. I suppose you might just quickly read about that just to be sure something somewhere along those lines might not be some sort of odd possibility.

Wishing you the best--
