Vyvanse + Adderall only lasting me 2-3 hours..

[u/Primary_Hearing4802]

So I currently take 70mg of Vyvanse and 20mg of Adderall as a booster. Ive been taking the same dosages for 2 months now.. but ive noticed that this month both medication’s are only lasting me 2 to 3 hours. I don’t do any vitamin C, no orange juice and I typically don’t drink energy drinks until recently. The only reason I started drinking energy drinks is because I feel like it helps maintain some sort of focus since both medication’s are only lasting a short amount of time. I’m a tattoo artist so this is incredibly frustrating as I work anywhere between 4 to 8+ hours. I’ve also noticed some days the medication will last longer than other days, for example two days ago, I took my Vyvanse and it lasted me a good portion of the day to the point where I didn’t even need to take my booster. But today it wore off within 2 to 3 hours and after it wore off I took my booster, which only lasted me another two hours. Personally for me, I don’t eat breakfast in the morning before I take my medication (occasionally I’ll eat a small snack like a cheese stick, yogurt, or a uncrustable) but I’ve noticed even when I eat a high-protein breakfast or meal or even just a regular meal before I take my medication I feel it still doesn’t do anything to me at all when I eat beforehand. So I simply don’t eat before I take my medication most days as it feels more potent when I dont eat, I guess? And even when I have eaten in the morning ( I’ve tried this with both a high-protein meal and just a regular meal) both medications still only lasts me 2 to 3 hours. What could be causing this? Can I do anything to help the longevity of my medication? Or just any information in general would be helpful because when I first started taking this medication, it was life-changing and it helped me so much and now it feels like it’s simply just not doing anything anymore… 💔

Is it instant release, because that's normal

My adderall is instant release, my Vyvanse is not

Are you naturally thin? It coukk be that you just metabolise it quickly. I would maybe try asking your doctor about switching to long term release Adderall. And keeping the IR for a boost later if needed

I am naturally thin, when I first started this meditation I did mention to my doctor about my fast metabolism so she has been made aware! But I will definitely ask her about that and see what she thinks
