I take sertraline HCL (zoloft) 100 mg two tabs each day. I have started to ween off of it by reducing to one tab per day. Now I am experiencing things like restless legs at night, lose stools, joint pain, sore muscles. I am 72 years old and in January I will turn 73. I have generally experienced reasonably good health, however I have high blood pressure (under control with 5 different meds) and a heart attach 7 years ago. I look 10 or more years younger than my age. My weight is 195 pounds and 5 foot 10 inches. Can my recent issues be caused by withdrawal. I am 70% disabled from the military, depression, anger, Iam also experiencing a mental alertness decline.
