I've tried 'all of the above.' Heh.
psychotherapy/counseling - This has been the best one for me so far. I'm currently seeing a counsellor. And it's been more helpful than any other method. The problem with this is that there are so many shrinks ill-equipped (I feel) to deal with PTSD. I've seen about 8/9 before I ended up here, to give you an idea. You have to be really persistent to find a good one sometimes.
If you find a bad one through the public system, don't be afraid to look around to see if you can find a compassionate psych who is willing to give you a discount, or only see you once a month. Sometimes seeing a decent psych rarely is better than seeing a crap one all the time.
medications - No luck with these. I've taken Zoloft, Effexor and Avanza. Effexor worked the best, but killed my sex drive, my creativity, and didn't do anything for the anxiety or the flashbacks. Ultimately it didn't really help much at all. The Avanza was HORRIBLE. And Zoloft was like taking candy that made me lose my appetite. There are no real good anti-ds out there for PTSD anyway.
herbal remedies - I think these can work in support with therapy (which for me, is a primary choice when dealing with a long term or ongoing mental disorder). It's important to know things like; St John's Wort can take over 3 months to start working and cannot be taken with other anti-depressants / the pill. If you want to use herbal remedies, I seriously recommend you strike up a relationship with a naturopath, rather than using self-diagnosis.
massage - Before my touch phobia was in full effect, this was very helpful. If you're a person prone to depression or anxiety touch can be very healing. Touch helps to release endorphins, it flushes blood through the system and better yet, it leads to more restful sleep and for people with anxiety - relaxes core muscle groups.
acupuncture - I used this to help wtih serious neck muscular tension, and it did help. But not enough that I'd get it again. Same goes for acupressure.
aromatherapy - Aromatherapy carries a few risks (ah the joys of working with essential oils) and it's more a support therapy than anything, but it can help. I feel. Not enough that I still use it though.
meditation/breathing exercises - These are fantastic. Especially for anxiety, and depression, or hell... *anything* really that leads you to feeling tense, uncomfortable etc. Breathing exercises create better equillibrium in the biological body, but can also help you to focus on your emotional state and/or still your mind. And meditation has been proven to increase happiness in all who practice it regularly.
homeopathic remedies - I still use homoeopathics to treat the somatic symptoms of my PTSD, like my irritable bowel syndrome. They work a treat.
Flower Essences (in my 'other' section) - I'd really recommend these, especially to folks who are sensitive to stronger medications. They are gentle, and specifically designed for emotional and spiritual ailments. In fact, both Bach and Living Essences have remedies specifically designed to aid with trauma, depression, and suicidal ideation. I love them.
Energy Work (in my 'other' section) - Don't underestimate the value of modalities like Reiki and Healing touch.
Phew! I'm done.
