I take Adderall, but it took my doc a while to dial it in for me: because I am a larger male she started me on a fairly large dose. To say I responded poorly would be an understatement: nausea and dizziness both. Violent nausea with no real warning. Ick! She dropped my dose down to a minimal one which did nothing to or for me. After all the adjustments I ended up on about half of the first one but in the extended release version which has been both working well and help my focus alot!

Oh, By the way, you may not need more as you become used to it. When I was working, I took 30mg, now that I am retired, 15mg is fine.

I was taking Concerta, but it doesn't work. I think I need a higher dose, but my neurologist's being an idiot. You're tired because you're depressed. Depression has nothing to do with me being tired. He keeps pushing for a sleep study, but I do sleep. My husband would know if I had sleep apnea. He has it. Oh well.
I do hope you can get something to make through the day. 🧡

I have tried other medicines to help with brain fog and fatigue and Adderall is the only thing that works. Everyone is different so something else might work for you.

I have found it helpful in my own case, but adjustment was necessary to find my right dosing. Because I am a larger man, the initial dose was too high. It also caused some adverse reactions, like nausea and it amplified the dizziness, or vertigo, that MS makes me feel. Then I was switched to a very low dose, which had zero effect. In the process of stepping it back up the Doctor put me on a extended release dose, which really was the ticket.
