anxiety
"I suffer from panick disorder. it seems to get worse every winter. I went to the doctor before it got bad enough to interfere with my life. My Doctor prescribed a very low dose od celexa again, which works wonders for me and hydroxyzine again because it makes me very sleepy and it really helps. I hadn't slept for 5 days because of heart palpitations caused by anxiety but this makes me sleepy within an hour. The only drawback is that I am usually groggy for the first couple of hours that in awake but I'll take groggy over insomnia any day."
