I totally agree with Jo about self hypnosis. When I had a panic attack at 5 1/2 weeks, I bought Rescue Remedy, and L-theanine and lemon balm and nothing really helped. I was worried for days afterwards that a panic attack would happen again. I had only had two others in my life and those were when I couldn't breath and the only lasted 1/2 hour or so. This time it was when I put my Xalatan eye drops in and they stung so badly. I'd taken these for months with no problems. The whole panic thing was related to the oxycodone and then the hydrocodone. I felt weak and fearful and too anxious to even read mysteries or medical stuff online. I'm totally back to normal now.
The only thing that helped a little was EFT. I know, I've scoffed at that ever since I heard about it a few years ago. Emotional Freedom Technique. If only they'd named it something else. I read the manual which I downloaded free. It's totally simple....just involving tapping on points of the body, kind of like accupuncture without needles. It is relaxing; it totally diverts your attention, just like the Lamaze method for childbirth (which I used when getting knee injections or going to the dentist). If something is bothering me, I can go through the routine 2 or 3 times and then roll over and go right to sleep. A few times I've started falling asleep while I was just doing the tapping mentally. At first I thought it didn't help, but I practiced it many other times and now it's fairly helpful.
