I have been taking Trazadonesince '94. The dosage was increased from 100mg to 150 a couple years ago. Now I have become extremely fatigued during the daytime. Ihave been told to skip a dose one night and then take 100mg the next night. The first night I skipped the dose, which was sleepless, I experienced hot and cold sweats, nasua, headache and severe weakness. The next night I took 100 mg but I still felt terrible. Should I wean off at a much slower rate?
