Just switched to vyvanse myself after years on concerta. I’m liking it, tbh.

But it’s not a switch. The effects are subtle, and often subjective - what works well for one person won’t work as well for others.

Also, are you “undiagnosed, but suspicious-to-confident that you have it”, or are you just taking this for a spin? If you intend on exploring ongoing pharmacological support for ADHD, I cannot in good conscience encourage you to do anything but get a diagnosis and work with a licensed professional.

The fact it’s having no effect on you probably means that you’d need a higher dose, since for a non-adhd person they would definitely be feeling that, BUT for the love of god go get an actual diagnosis and a prescription

It's not magic, to be fair, though you very well may be at an inappropriate dose since you self medicated.

Generally you'd expect it to 'help', but not a silver bullet for all your productivity needs.

Talk to a doctor and get a real prescription and work with them to dial in your dosing.

These medications also take time to settle in. You should use a correct dose for at least a few weeks to see how well a certain molecule affects you.

Get that diagnosis, talk to a doctor. The hard way is often the better way.

I personally found that Vyvanse did two things: raise my heart rate to unsafe levels, and allow me to focus easier without the ability to choose what I focused on.

Different meds work differently for different people. Or if you aren't actually ADHD they may be less effective for you. Better I ask a doctor, but Adderal works best for me.

Effect can vary a lot. I did a tolerance test with 5 mg, and even that was mind blowing. Effect was short, but my executive dysfunction was completely fixed. I cleaned, worked out, did calls and wrote letters I had been putting off for weeks. It felt like a fantastic dopamine shower.

Then, for a long time, I went with 10 - 15 mg. Slowly working up to 50 over 6 months.

The "mind blowing" effect is really fading hard one year later, though. I'm pretty sure that it's not really what the doctors want. They want regulation of dopamine and noradrenaline in the prefrontal cortex, which is a benefit that does not diminish over time. What gives the amazing feeling is excess dopamine in other regions of the brain, like a recreational drug, and that fades.

The first time I took prescribed Vyvanse on the lowest starting dose, it changed my whole life 180° for the better. Best 2 years of my life. Only 2 years because toward the end it wasn't working anymore, just headaches. Withdrawing from it was heinous suicidal depression and SO MUCH OVER-EATING. Got through it though. Still alive.
