Hello, this is Dr. David. I have read your question and I'm ready to help.
why are you taking the prozac? are you taking it to treat depression or excessive anxiety symptoms?
you should never stop taking prozac suddently
since you have been on it for so many years, you have to talk to your doctor about a very very slow taper schedule to come off of the prozac so you don't get withdraw symptoms.
and also you have to know that if you were taking it for depression, if you taper off if it, your depression could get worse
if you take the prozac to help fight anxiety, your anxiety could get worse if you taper off off of the prozac.
you need to have your thyroid
hormone levels checked as well.hypothyroidism
or low thyroid hormones could cause you to gain weight
have you talked to your doctor about your weight gain?
have you had your thyroid hormone levels checked?
