I'm very sorry to hear this iaccus. I'm right there with you.
I won't tell you how bad they are with me, as I fear trauma by proxy for readers, but they have become less frequent. They were pretty well rare in the days of drugs and alcohol, but once I disclosed and began addressing stuff without substance abuse, they became .... well ... nightmarish, and very regular. Now, its about 3-nights per week. Daytime flashbacks have dropped WAY down over the past 8-years.
My Psychs in hospital and out have prescribed drugs to help. Imagine that! I was right all along. Drugs. Hmmmm. Cept now, they are covered by insurance and don't involve meeting a guy in the fourth row of the Starbucks parking lot with a stack of cash.
The biggest (legal) help has been Klonopin. You might wanna ask your Docs as soon as possible.
Send me a PM if you need any further info or treatment history.
