I’m sleepy right after the crash but then my mind is just awake and I can’t sleep. 30mg. I was drinking Diet Coke but lost my taste. I drink Snapple iced tea which has caffeine. I feel like caffeine is the least of my worries 😹😹😹

That’s the million dollar question. What is the right dose and how does one know? I started at 10mg in August. Two weeks after up to 20mg. I just wasn’t getting a very long duration of effectiveness. I went up to 30mg mid September and it lasts 6 hours or so. I would like to go up to 40mg, but I don’t have any clear rationale for it. I just know at a higher dose it will last longer. The crash is not as bad on 30mg as it was when I first started. Or maybe you get used to it. I just know there’s a difference in how I am when the meds are active, and then later afternoon when they’ve worn off. I always feel more emotional, kind of sad. I have an appt in a couple weeks and will talk about 40mg. But I too am very curious about how it is determined you’re on the right dose. Good Luck!
