Prazosin
"I started by getting sick after eating, then nightmares, sleeplessness, panic attacks, agoraphobia, high anxiety, and being diagnosed with post traumatic stress disorder. I was put on different medicines by different doctors and nothing worked.  The different meds made me gain 40lbs, gave me diabetes, dyskinesia, and SSRI's have horrible withdrawal symptoms when you run out of medicines. A new VA doctor recently prescribed Prazosin. After three days, I no longer felt like I was constantly shaking inside me. I don't feel like a speaker reverberating through me when I hear a loud or sudden noise. I went from sleeping 4-5 hours per night to double that. I don't have nightmares anymore, and I stopped getting sick from anxiety. Prazosin is a miracle to me."
