I took Concerta for first time today at 36mg and it was a very rough experience. I took 2 hours to kick in and despite drinking tons of water i had a head ache all day. I felt alert but not super focused, and I was still forgetful at work. Things just didnt seem right all day. I became more emotionless and less happy as the day went on, and when i got home from work at 5pm I actually cried for no particular reason. after crying i felt way better and focused very well on some homework. Now I feel much better but am surprised at how up and down i felt the entire day. will these mood swings change or will I continue to feel kind of sad?
