Recent diagnosis

I was diagnosed within the past 6 months at 30 years old. Which was brilliant and exciting. Since then we’ve been trying to manage symptoms that are hindering me daily with medication. I began on 40 mg of strattera. Moved to 60. Moved to 100. Not a lot of relief. I began Ritalin on Saturday so yesterday and I’ve had the worst headache for two days. Is this common? I’m assuming it may be just due to a new medication adjustment. I’m still learning so much but don’t have many people in my life to ask… just wondering if anyone else experienced this!
