I've only been on Remeron (15mg) for a week, but I'm sort of the impatient type. I am wondering when will the intense grogginess lessen? It's not the type of sleepiness where you can take a nap to get rid of it. It lasts about 10 hours. I feel somewhat detached from my body and noises seem far away. It isn't an unpleasant feeling because during this, my anxiety is completely gone.
