Do any ADs (or anything else) help with nightmares?

[LadyOfWaffle]

I am getting horrific nightmares at the moment - I get them from time to time but these have been nightly. I am pretty sure it's my depression/ptsd etc coming out in this way so was wondering if going back on the ADs will help this? Or is there something specific? I am breastfeeding too (6m in a week)

I find listening to a relaxation CD (when I remember to bring my Ipod up to bed)gives me aquiet night.
Don't know if they're the best ones, but mine is from www.virtuallyperfect.org. They have them for stress relef, anxiety, sleep, loads more.
