Frustrating thing is you have to experiment until you get the right combination and dosege. Give it at least a week or two, but different people react to different mixes and doses, and for some it takes time to settle with the effects. Methylphenidate works for most, didn't for me from one company, I had better results with another one but in a version with some milk byproducts, which I cant consume. Ended up on another group of stimulants with a second med in "support role".

Probably stick to your prescription and tell your doctor how it's going. Titration can take time, and you'll get better results if you're consistent and methodical.

Well, I don't know if I can give advice but I can at least share my own experiences with those drugs, such as they are.

I can't speak as much to the methylphenidate because I haven't taken it since I was a kid, though I will say I didn't notice it changing my behavior at the time. But then I was never very self-aware in that way as a kid, and the adults around me claimed to notice it had a substantial effect on me.

As for the atomoxetine, though, I was on it for about five years as an adult, and I can say that it is a slow buildup kind of drug. I think it took maybe a couple weeks at least for me to start seeing any beneficial effects. It wasn't a constant "on" like adderal, instead it felt like my brain was finally willing to make an appropriate level of dopamine when I was doing something that needed it, which seemed like how brains are supposed to work.

Brain chemistry can be a bitch to get lined out. Especially when parts of your brain aren't doing their job. I'm almost a decade post diagnosis and my quality of life has improved dramatically. It's not perfect and I still have to tweak things occasionally, but it's much better.

Everyone reacts to stimulants differently but the effects are usually noticeable pretty quickly. Keep taking your prescribed doseage and talk to your doc about it. I've never taken methylfenidate, but I've been on Vyvanse for years. Adderall was too rough of a ride for me. It took probably 6 months to get my dosage up to the right level. The main problem I'm having today is that it exacerbates my motor tics. Still working through that one.

Hang in there. If this stimulant doesn't work well for you, there are others you can try.

Took me about a year of changing the dosage until I got it right, but rhe emotional stability is a real life chabger

Atomoxetine suddenly stopped working for me after about 6 months. Methylphenidate just made me feel off. Lysdexamfetamine (Elvanse) was the ticket. I stopped taking it years ago and now only take a fractional dose very occasionally, only when I absolutely have to.

Increase dosage

One made me feel sick and the other I skipped over. I'm taking a expensive medication right now call qelbree which is similar to atomoxetine. I've had good results to it but had a hard time getting it approved by insurance.
