I am 6 days on 20mg of Amitriptyline for sleep and GAD. So far the terrible headaches have worn off, I do not have any side effects except for some tiredness but aren't sleeping very well even with the meds but my anxiety seems to have heightened somewhat. I know this is normal with most anitipressants.What dose did people take and settle on for helping with GAD? This is kind of my last chance now as I have tried so many drugs that have all failed and 17 months later still cannot even go out apart from to my doctors or to rush into the local shop and out again. I was given this a few years ago but after a week went onto Citalopram as I went fine then had a huge panic attack. I often wonder if I had stuck with it would it have worked as there is little on the net really but what I have found is that despite it being an older type AD, it works just as well as SSRI's which I need basically knocking out with benzos to tolerate.
