Medication is a really personal decision and I have had both good and bad experiences.
At the present time I am complete free of psycho-pharmaceuticals. I have made major lifestyle changes and really make sure that I eat right, hydrate, exercise, meditate, sleep, and keep stress to a minimum. Everyone of these things has helped me to stabilize and to find balance and enjoyment in my life. Therapy has given me the tools to manage PTSD symptoms when they arise and at the present they are not much more than a few blips on the radar.
But this past year has also taught me something about drugs and really changed my mind about using them when they are needed. For almost a year I have undergone chemotherapy and that therapy also required the use of steroids. Never have I had anything kick the PTSD up like steroids did, and at first I was very non-compliant in using medication to offset the steroid effect, because they were benzodiazepines. I will never again put myself or my family through that.
So personally I live just fine without medication, but there are times I have needed it. I guess my advice would be to not take mediation if you really can do without it; but don't rule out taking it completely, because you never know when you might need it.
