I tried taking serzone for a little over one month. I started with a very low dose - 75 Mg, and my doctor wanted me to work up to about 150 mg/day. Unfortunately, I was never able to get there. I had a whole host of interesting side effects - head feeling hot and cold, drowsiness, terrific technicolor nightmares (including an interesting one where I was crucified) a general feeling of fogginess in my head, reflux, and insomnia.I found that I could alleviate the insomnia by taking the meds in the afternoon, since taking them before bedtime only put me in a weird mode of being half asleep.What I am on now is doxipen/sinequan. I've been taking 25 mg/day for about 1.5 months now. It definitely does the trick, and helps me sleep to boot. I have had no side effects.
The doxipen route might be something you want to consider, expecially if you also have insomnia, and are the D type.BTW, I don't know if you still run, but I am a runner too. I've found that the running aggravates the D, and the doxepin really helps on the long distance days.Bob
