Concerta
adhd
"I've been taking Concerta XL for around 2 months after finally being diagnosed as and adult. I started on 18mg, and within half an hour, I felt able to concentrate and focus on tasks for the 1st time. A couple of days later, I had crippling headaches but everything settled down after that. My resting heart rate has sped up by 10bpm whilst the medication is in effect. I'm currently on 54mg and the therapeutic effects are great, but I feel dehydrated no matter how much water I drink, and I have developed sinus problems. It's worth it though."
