Side effects of Remeron may include very weird vivid dreams, feeling exhausted, confused, dizziness, vertigo and increased appetite. I have read that the vivid dreams may stop after your body becomes use to the medication.
Most of the patient comments state they either love the medication - that it gave them their life back or they could not tolerate the side effects.
Like most of the medications, each person reacts to the same medication in their own unique way.
