coopsmom,The starting dose for Remeron is 15mg at bedtime and I have read of people sleeping through the night but their body adjusts to the med fairly soon. I do not have personal experience with this med but I too did not do well on Zoloft and it made me feel worse just as it did you.
I hope Remeron is the medication that will help you. For the first week try not to plan any big outings etc. Just give your body a chance to adjust to the med change.
Keep on talking with us.
