I have been on 20mg of Lexapro for the past year. I started having brain zaps, tingling in arms, weakness in body, and lathargic feelings during the early afternoon of each day. I usually take my Lexapro at 5pm everyday so i think my body may have started to have withdrawl early in the afternoon. So i tried taking them in the morning at 8am. The brian zaps and tingling are gone, but i can't express how tired i am throughout the day. My body feels like it just wants to sleep. I feel like my muscles are week and i have the shakes in my hands. Has anyone experienced anything like this? Is it time for me to get off this medication or try something different? Mentally i am not depressed, but have NO energy. Help!
