I feel like I never eat…

I’ve been taking Concerta 54mg for almost a year now. My doctor slowly raised my dose and the medication seems to be doing exactly what it’s supposed to. However, when I get off work at 6pm I tend to be very irritable and have horrible brain fog and fatigue. Typical signs of hunger but without the hunger. Some days I go without food until almost 9pm without even realizing it. I’ve never been a breakfast morning, it usually makes me nauseous eating so early. So I’ve started incorporating protein shakes or smoothies into my diet as a meal supplement. But I’m still not feeling like myself in afternoons/evenings.

I’m starting to get concerned that this will have negative side effects long term. It’s as if I’ve been fasting for 12 hours each day which I feel isn’t healthy for a 22 year old 117 pound woman.

Has anyone else struggled with this, are there any other ways I can try to combat this side effect? I’m just tired of feeling so exhausted for the second half of every day.
