Hello ......
I have been on Lexapro (20mg generic) for about 2-months now - and I find it to be very helpful in lowering my high emotional levels. It has tempered my highs without affecting my lows noticeably.
This is the first anti-depressant I have ever taken - so my point of comparison is not good. I have been on a hormone therapy for almost three years, so that has played with my emotions AND with my energy level.
The Lexapro itself may affect my energy - but it is too hard to tell because of all the other meds I'm taking - mostly cancer meds! The side effects I have had have been very minimal with Lexapro .... but again, the side effects of the cancer meds have probably disguised the Lexapro SE's!
Summary ...... the Lexapro has done what I was expecting it to do ... by calming down my emotional highs.
Some have said that side effects, if any, may disappear in a couple of weeks. Most have said - give Lexapro 4 to 6-weeks to work .... although I felt some relief within two weeks.
Best of luck to you.
