I will definitely contact my neurologist. Thank you

This is the recommendation of the drug manufacturer. The patient should not decide on the change of dosage on their own. Frequent changes in treatment strategies may cause: 1) ineffectiveness of therapy, 2) worsening of side effects of drugs, 3) worsening of symptoms of the underlying disease. Before you start changing the treatment proposed by the specialist, please contact him/her. I also encourage you to take advantage of psychological therapy to help you survive the more difficult periods of treatment. You can ask the doctor treating you about the possibility of implementing medications to further improve your mood.

I understand the specific time of 2x4 weeks, how do you wean 250x500 for 2 weeks 250x250 2 weeks and 250 for 2 weeks at night?

If the symptoms are so severe, you should go to the hospital. Stabilizing the disease in hospital conditions seems to be the only way out in such a situation.

And every week like the symptoms intensified
