I started taking 10mg twice a day of Ritalin about 6 days ago and Ive been twitching my toes all day. I just keep curling them thru out the day and is starting to bother me. Im wondering if taking 30mg of lexapro with the ritalin will put to much serotonin in me. The doctor wanted me to put me on Vyvanse first but the insurance wouldnt cover it so the doc put me on the ritalin. Would a different medication work but stop the toe twitching im having?
