I'm on 10mg of Ritalin 3x a day for treatment resistant depression and it's just making me sleep all day. Has any one else had that experience? Is the dose too low ? I've tried every antidepressant, mood stabiliser there is over the last 20 years . I've only been on it 3 days, does it take time to work? I thought it worked like an amphetamine and worked within 1-2 hours?
