Need higher dose: You may need to ask your docotr to adjust the dose up. If higher dose is not effective enough to control your add or adhd, then you may want to discuss a change of medication. Keep in mind that your weight and fat percentage plays a huge factor plus the way you are taking the medication plus the acidity level of the stomach secretion plus the ph level of your body.
