MM,I gather you are taking your Prozac at bedtime? A couple of things - look at having your Dr. reduce your dose a bit. Take your Prozac earlier in the evening so the side effects wear off sooner the next morning.
Just having had pneumonia may still be causing your body to feel tired and exhausted. So take plenty of time and eat healthy to get back all your strength.
I am glad the medication is helping with your anxiety.
Kindly,
Kitt
