The most common side effects of Sertraline that you should watch out for are nausea, diarrhea and sleep disturbances,
in that order. There are a lot
of other side effects listed
for Sertraline, but these are
the ones commonly encountered. Drowsiness and excessive sleep may be seen with Clonazepam. Other side effects are rare.
I won't be able to comment much on the effects of the initial dosage on your blood pressure, as it differs person to person.
