I often struggle with rushing out the door in the morning without grabbing something to eat. I have had this problem as long as I can remember. This changed when I started taking medication to treat my ADHD symptoms. Without a full meal, the duration and effectiveness of my morning dose would vary. I needed a solution.
I started doing meal prep once a week. Sometimes I make 4-5 days worth of breakfast burritos or a big batch of hash browns with veggies I had on hand. Healthy trail mix as a meal replacement is a good option if I'm in a rush (I like Power Up High Energy). It is ready to eat, doesn't require cooking or utensils, and is shelf stable at room temperature. I keep some in my work backpack and at my desk in case I miss lunch. What hacks work best for you?
Grapefruit juice. Always and for ever.
(disclaimer: DO NOT take meds with grapefruit juice as it can have a massive effect on how fast your body absorbs the medication...)
... Though I bring it up to point out that the "best" meals will be extremely basic and uncomplicated foods. I'd avoid most things, if it's important meds that need to remain in balance. If it says you do not need to take it on a full stomach, I'd avoid food around such times.
I hope a biologist/biochemist/etc can chime in on what foods are least likely to directly fuck with meds, since as far as I remember, a ton of it is about simply buffering out the meds with filler and digestion time, which a lot of food should fit.
