Hey, im new here

and im 23 years old, i figure i have A.D.D cause i have a hard time sitting down trying to study without me having to get up and doing something before returning to studying or trying to finish a assignment/project. I wished i had gotten checked for a.d.d before i started college, probably would of helped allot with me getting a higher GPA, right now im preparing myself for the gmat to go for my mba degree,and im just not focused, i have free time and instead of trying to study i end up moving around, eyes wondering off, not really understanding what im studying ... What type of doctor should i visit to check for a.d.d and hopefully get prescribed some adderall, im not trying to spend that much $$$ on a doctor that is a specialist in that field, i heard there are different numerous doctors that can prescribe u
