Mood is stable but having fatigue and drowsy

My medications help me with my moods. I'm trying everything that will help with the fatigue and drowsy. I don't know if my medications are causing the fatigue. I'm taking B-complex vitamins for energy. I am taking Trazodone for sleep. I might need to lower my dosage. I will ask my p-doc about lowering my dosage. I'm also take Geodon at night and I take Pristiq in the morning. I remember my pdoc said that I can lower my dosage of Trazodone if it is too much for me. I might try that. I'm taking 200 mg of Trazodone at night. I might lower to 100 mg and see if it will helps.
