What does it feel like for you when you've used any ADHD medications? I have looked at a bunch of 
posts but I feel like there are never good answers for this. I have heard that they can help NT people with focus and such, or that y'all build up a tolerance after a bit. And then I hear for people with ADHD, that the first couple of times you take the meds, or if the dose is too high, that you'll feel speedy/high.
I've been trialing meds with my psychiatrist for a while and I feel like I don't even know if I have ADHD because of all this conflicting info and how I feel on them. I know it can take a lot of trying different types and doses but I just doubt my diagnosis I guess.
TL;DR: What do stimulants feel like for you've taken them semi-regularly?
Isn't it possible to be diagnosed ADHD and not benefit from stimulants?
Absolutely, yes. There are non-stimulant medications that you can take for ADHD such as Strattera. The success rate of those is much lower than with stimulants, but when they work for people, they can REALLY work. Some people don't find relief with any type of medication, too. Rawdogging life with this diagnosis suuuuuuucks though
Definitely, there are several subtypes of ADHD and stimulants don't work equally well among them.
