I am not a medical professional and would not be able to give you medical advice.
It is always suggested that you talk with your doctor before stopping any medication.
Most people do not experience any problems when stopping stimulant medications, however, if you have been on a high dose or been on this medication for a long time, you may experience some withdrawal symptoms such as headache or fatigue. If you do, you should talk with your doctor. He may want to wean you off the medication, slowing it down over time before taking you off it completely.
