Very med sensitive, so I am always have to take the lowest dose..I am on liquid citalopram. Today is day 8..The first 6 days I was at .5ml, which is only 1mg, yes 1mg..Please don't laugh Now I am on 1ml, so 2mg..We are trying to get me to 5mg..Has anyone had success on such a low dose..by the way, i still have SE, such as nausea and dizziness...I know there are studies out there that state some people need 2.5mg of a ssri and some need 40mg..Would love to hear from someone in the same boat as me...thanks, debbie
