Psychiatrist recommends 75 1/d but general MD wants it at 37.5 2/d. Have been on 75 1/d for 2 years and it keeps severe depression at bay. Have gained 40 lbs since first depression which was sudden and unrelenting. Two other meds did not work but for 1 year each and had to be changed. No question but that meds have saved this life. Just wondering who to ask about dividing the dosage.
