question: I have been taking Prozac 10 mg x 3 yrs,  I wanted to stop taking it.  When I told my physician about it he strongly advised me against doing this.  He then increased the dosage 1o 15 mg.  I do not feel any better, in fact, I feel worse. I still cannot sleep at night without chemically inducing my sleep. My doctor then advised me to take Melatonin po  qhs.  This puts me to sleep but I still do not feel less depressed at all. Could the increase in dosage agitate my sleeping even moreso, and supress my appetite, make me feel nauseated and off balance.  I have only been taking the increase dosage x 1 week.  Please advise.  thank you...
