Taking meds later = effect lasting later?

Hi everyone,

Do you feel any impact if you change the hour at which you are taking your adhd meds? Like, if you take it later, do you actually feel like the effect lasts until later as well? But can you still start your day? No impact on sleep? Any other feedback is also welcome!

Also: anyone here having feedback on combining ritalin + medikinet?

Thanks!

Some context:

I've been prescribed 20 mg of ritalin in the mornings during week days. I've been told that it should last a half day. My doc prescribed me 10 mg of medikinet if I feel I am getting tired after 5 hours. I am not sure if this is needed (and no super excited about the idea of adding yet again a medication to my list), so I am starting from today to experiment how taking my meds later in the morning would impact my day. In general, I don't feel like I am "crashing" in the afternoon, I just feel like I have a bit less energy. I rather feel the difference on weekends when I don't take ritalin and I am yawning all day!
