I've been recently diagnosed with adhd at the age of 28. I've been taking 30mg Adderall xr for about 3 weeks. I told my doctor that I haven't noticed any big changes, so she decided to switch me to focalin xr 10mg. She suggested that I not take the adderall for a few days before taking the focalin, which I did. In that 2 day span of no meds, I realized how much the adderall was actually helping me. So the 3rd day of take my first dose of focalin and it was one of the worse experiences of my life. I couldn't think, I could barely speak or function. I felt so sleepy that I had to leave work because I was afraid I would injure myself or someone else ( I work with heavy machinery so it could've been really bad for me to stay) when I got home I passed and didn't wake up for 12 hours. The next morning I feel fine just a little cloudy and unmotivated. Then I took my Adderall again and I feel great. Has something like this happened to anyone else?
