I've been put on Mirtazapine/Remeron and I been having extremely vivid dreams. I take it at night to help me sleep and it does help. I'm also coming off of Effexor, I take 75 mg this week and next week I'll be down to 37.5 mg. I was wondering if the combination of withdrawals from Effexor and Mirtazapine are giving me these crazy dreams. Does anyone else experience anything simila? . Thanks.
