... a light sleeper but never as bad as recently)It got to the point where i could not nod off no matter what so after getting a physical and finding nothing wrong they said I had an anxiety problem and was given cipralex 10mg. Been on it for 17 days, doctor now said to go to 20mg. I finally started to sleep a bit at night these past four days but I noticed that my cognitive functioning is slower as well I dont have the energy levels that I used to have, I feel like my IQ has dropped and im terribly fatigued. Will all this go away? Its better than not sleeping but I still cannot function normally with these (i think) side effects? After 17 days im hoping the tired feeling will go away, did anyone experience fatigue and slower mental functioning? please advise?
