I have been on paxil cr12.5 mg for 6 days and last night was the first night I just took paxil,10mg so a total of 7 days now, my anxity is worse than ever, cant sleep with out waking up quickly and feel very antsy, dry mouth, can't eat and just feel awful. How long do I have to go through this? Mornings are much worse than the evenings how come?
