Also, you have to take into consideration that
dosage increases may be necessary too (you were on a fairly low dose of the
Lexapro), in which case you would have to give the med another 4-6 weeks from the time the dose is increased. It can be a lengthy process. Keep these things in mind with the Zoloft, so you give it the best chance of being successful.
Hang in there...you'll feel better soon. Keep the lines of communication open with your doctor, let him/her know what is going on.
