Update - been taking the Citalopram for the past five days and have had hardly any sleep, extremely dry mouth, loss of appetite but worst of all, horrendous anxiety and panic attacks - this morning I have been awake since 1.57; I appreciate these tablets haven't kicked it yet and that, hopefully, long term they will help me. I have had to take today off to try and get some sleep as I feel so spaced out. My star of a husband has been awake with me all night, talking to me to try and calm me, stroking my hair and just supporting me. I don't know if I will be fit enough to work for the next few days - feel like closing myself off to the world and hibernating (if only I could sleep!). My memory has also been getting worse and whether the anxiety is making me feel this I don't know but I am starting to seriously think I may have early signs of dementia...maybe that is the anxiety......
