Ritalin doesn't affect me, is Adderall better?

I am 19- almost exact same experience. I know I have ADD but this isn't working very well. more easily irritated, more gregarious sometimes.

I am 24 and recently diagnosed ADHD and I did the same thing you did. Started off with 5 mg, upped it to 10 mg. Later I added another 5 mg and still no reaction other than I feel like clenching my jaw and grinding my teeth a lot and I've never done that before. I also have a dull, annoying headache and my eyes feel heavy. I think I will try to up it to 15 mg at one time tomorrow morning. The insert says that it takes about 2 weeks for the effects of the drugs to actually work, so I'm just gonna keep at it and see how it goes.

I don't know tho, my doctor said that it should be pretty much instant. I heard that if ritalin doesn't work, that adderall should, as it lasts longer and has less side effects. I dont' know why he just didn't give me that in the first place... guess we'll see in a few weeks.

Day 3 on ritalin and I feel like the ritalin helps with my hyperactivity whereas the adderall helps with the focus.

Do people prescribe them together, I wonder?

I was diagnosed with ADD when I was 17 years old. My doctor decided to put me on Ritalin and the ONLY thing it did was make me angry even when there wasn't a reason to be angry.
I talked to my doctor about this and he decided to switch me to Adderall 5mg. Thankfully, it didn't make me mean or anything like that, it actually helped and I could tell a difference pretty soon after I started taking it.
If I were you, I would talk to the doctor about switching you to Adderall. I know that everyone's body chemistry is different but for me, Adderall is THE best!
Best wishes to you and good luck!
