My medication for anxiety and depression,started a year back . My psychiatrist have given me to start with nexito 10mg, after around 6 months of daily dosage it was reduced to 5mg , I felt horrible right after a day of reduction. But soon after that everything got into place , Now my psychiatrist have reduced my dosage from daily to alternate days and again I feel the same but in a reduced scale , right after a day of the skipped dosage, I want to learn about the half life of the medicine and learn to be strong through my withdrawal process.? How long should I wait and what to expect.
