Meds are not a terrible place to start, though I always suggest that you research everything you are prescribed. Especially if you are looking into medication as a more short term band-aid approach.
A lesson I learned the hard way this last year, the technical definition of "addictive" apparently only applies to chemicals that cause damage to you (or something semantically rubbish like that). Either way, having to face weeks of withdrawal symptoms when you weren't expecting to is not fun, amusing or helpful for building a trusting relationship with your physician. (Now I'm projecting, sorry. Still a bit bitter about that.)
Anyways.
Prazosin is one of the anti-nightmare meds commonly prescribed, works pretty well. It is an "off label" use of that drug. It is normally prescribed to treat hypertension (high blood pressure). Can make you very lightheaded, dizzy and prone to fainting the first few times you take it. Stand up slowly. can also cause tachycardia (rapid heart beat).
The med I used to swear by, untill it inexplicably stopped working (no idea why).
Amitriptyline is a tricyclic antidepressant. Has the added bonus of being quite sedating, apparently also works to supress nightmares. I never found it did that very well, but when it worked for me I slept well. Also made me hungry as anything, I put a fair bit of weight on with that drug. Went from being emaciated to human, not bad for me, but something to note. Also (this is definitely different for different people.) I could quit the stuff on a whim, without any noticable side effects other than, rebound insomnia. Made it my go to band-aid drug of choice.
Weed? Makes me nervous and paranoid. No idea how that would work, don't use it myself.
Time, while your immediate upleasant anxiety symptoms may decrease as external stressors lessen around you. PTSD is a wound time does not heal, sadly.
A couple of ideas, hope you find some use in them.
