HI Tara,
I was on the Lexapro and started at 10mg and did not have those side effects, however after 3 weeks it still was not covering my depression and anxiety so I went to 20 mg..............finally gave it up and then ran through a bunch of others.
I am now on Cymbalta at 120mg devided into 2 doses per day. It seems to be working but it may be the combination of the meds I take. I do feel I am a bit overdosed on it and in August my Pdoc and I are going to decide on backing off to 90 mg per day.
Most of the time it will take 4-6 weeks to get the full effect of your med but if you cannot tolerate the side effects please talk to your physician.
We are here so please keep us posted.
Gentle Hugs.
