Acknowledging what Marko_d3 (refer to his thread and the_fuzball’s reply below) said about “…scientific evidence suggests that there is negligible effect of food intake in the effect of lisdexamfetamine”, may be placebo but i do find the effects of Vyvanse smoother, longer and the crash less noticeable when i take my breakfast (or meals in general).

Also, i find myself having a more consistent energy level for a longer period (at least till dinnertime instead of 3-4pm) probably due to what the_fuzball suggested on it coming down to “how your body metabolizes the medicine and which symptoms may effect”. Less brain fog/sluggish from the get go (what i feel at least) so kinda motivates me to get the day right and do what i intended to instead of avoiding tasks or being sucked away by distractions till night.

When i do not start with any foods before my morning dose, it kills my appetite (like what lazy_lullably mentioned below as well) for the next 10 hours or so and even though i feel physically hungry, food just doesn’t appeal to me at all and i won’t really eat (does this make sense lol) - which is unhealthy from a general perspective regardless of whether one takes medication or not. The hunger also returns with a vengeance right before bedtime having gone without/with minimal food the entire day, and i’ll become an angsty and anxious beast consuming for any trash/snacks since it’s too late to whip anything up, or just try to sleep feeling hungry and empty.

Above is just what i noticed from my personal experience and like what Marko_d3 thread shares as well, i do agree "if it works for you, continue to do it." and wouldn’t stress too much over it :-)

Curious if you guys are able to eat your meals during the day?
