Concerta
"I have been using Concerta for 15 days now. I started out with 18mg for a week and the second week 36mg. I haven't seen any difference by now, which is very dissappointing for me. In fact I feel slighly extra depressed than I already am, but no big difference. Starting tommorow my doctor told me to take 54mg per day. Any suggestions? Is it too soon to see any difference?"
