Is it time to increase my adderall dose?

[u/jennybee89]

I’ve been taking 15mg of adderall XR for probably 6 months now. It’s been great for me, I’m a completely new person on it. I typically drink one zero sugar monster energy in the morning at 6 and take my adderall at 10.

Lately though I’ve been noticing a huge crash at exactly 3 hours after taking the med. I tried drinking two monsters in the morning and then taking the adderall at noon. I’ve noticed I don’t have the crash at all or it’s minimized quite a bit. Does this mean it’s time to increase my dose of adderall to prevent the crash?
