Need a dose change AdderallXR

Hello I just started adderall XR, and its working great!! but my dose is so low i think.. ive already taken it upon myself to up the dose by double !! so i now take 40mg of 10mgXR.. I know i need to go back to the right dose.. i just started 4 days ago!! is it to early to call my doctor??   anyone who could share about how they started a low dose, and it didnt work, and what they did or didnt do to help it!! thanks a lot!!  ( even if it was against doctors orders)

I look forward to becoming a reg, on the board

WOW YOU DOUBLED IT?  YIKES!  I STARTED ON 10 MGS ALSO ABOUT 8 DAYS AGO AND YESTERDAY I OPENED A CAPSULE AND USED ONLY HALF IN MY YOGURT, DONT BITE THEM THOUGH CAUSE THAT WILL RELEASE ALL THE MEDS AT ONCE!

I THINK YOU CAN BUILD UP A TOLERANCE IF YOU GO UP TOO HIGH AND TOO FAST!  YOU SHOULD TALK TO THE DOC THOUGH...ALSO IT DOES TAKE A GOOD TWO WEEKS TO REALLY GET INTO YOUR SYSTEM TO TELL IF IT HELPS ANYTHING SO I THINK 4 DAYS WAS TOO FAST BUT THAT IS ONLY MY OPINION.

I KNOW I WAITED A GOOD WEEK THEN ONLY WENT UPU 5 MGS AT A TIME AS I DO NOT WANT TO GET A HIGH TOLERANCE TO IT EITHER.
