At work, I usually take my 2nd dose of adderall with lunch- do you guys who do this find that taking it with food decreases or effects its effectiveness? I try not to eat much vitamin C in that meal.

I can definitely tell a difference in its effectiveness after I have eaten. Its kinda hard to work your adderall in around a meal (at least for me) because I always try to leave an hour gap to let my food digest.

This I would suggest or have heard of others doing:

1. Take a few antacids either with your meal or 20mins before you take your meds. This will reduce the acidity in your stomach and increase the absortion of the medicine.

2. Take vitamins that increase the effectiveness or absortion such as magnesium (which is like the same thing as an antacid).

3. Try to wait an hour after you eat to take your meds

4. Take a digestive enzyme with your meal

what about taking the adderall like 15-30 minutes BEFORE I eat.

Would that be better/worse then taking it with food or 30 minutes after?

I would say take Adderall 30 minutes before you eat, since I imagine you would metabolize the drug faster than you would digest a meal.
