Timing really makes a big difference with Modvigil — taking it later in the day almost always ends up messing with sleep.
When I take it early in the morning with food, the whole experience feels much smoother and more balanced.
For me too, it’s not about feeling overly energetic, just staying mentally less drained throughout the day.

how most people focus on the dosage, but timing ended up being the biggest factor for me too.
When I first started using Modvigil, I assumed it would work like coffee and wear off by the evening. Turns out that's not how my body reacted at all.These days I treat it as an early-morning thing only. The focus is still there, but my evenings feel much more normal. If I take it too late, I know there's a good chance I'll be staring at the ceiling wondering why I'm not asleep yet. Definitely one of those lessons I had to learn through experience.

That's exactly what surprised me as well.
When I first heard people talking about Modvigil, most of the discussion was around dosage, so I assumed that's what mattered most. After using it for a while, I've realised that sleep quality and timing probably affect my experience more than anything else.If I've slept reasonably well and take it early, everything feels pretty normal. But if I'm already sleep deprived, it sometimes feels like I'm borrowing energy from tomorrow I can get through the day fine, but then I end up feeling completely wiped out later on.
Interesting to see that so many people seem to have reached the same conclusion through trial and error rather than figuring it out from the start.
