I had my dosage of citalopam upped to 40 from 20 six weeks ago as my anxiety seemed to go through the roof.The last few days have been dreadfull ,and last night the panic kept me awake and its still going on now Has anyone else encounterd this or have the citalopam stopped working.I have been taking them for a very long time but only 10ml until just over 2 years ago when they were upped to20.Sorry if this sounds barmy it is my first post would be grateful for any advise
