That makes sense, he started me on 20 mg for a month after that period i told him that they seemed to be having no effect on my depression, i believe now that they simply hadn't had time to work, and that is when he advised me to increase the dose to one and half or two tabs or drop back to one if necessary, i think the idea was that i take an increased dose for a period of time and reduce it if need be, not to change it on a daily basis. i did increase them to 40 mg on his advice but found that they were making me tired all the time and my anxiety was starting to return. i have now gone back to and sticking with 20 mg they seem to be working. thanks for the reply and sorry if my initial post was misleading.
