Adderall XR - no effect on me?

[tehpharmacist]

Hey,

SWIM bought 10 of the 30mg Adderall XR capsules a few days ago.. it was SWIM's first experiment with Adderall.

He took one 30mg XR and within an hour he was feeling a high similar to an XTC buzz.. but different in a way.. either way, he felt very good, and very talkative, as he feels on XTC.

After about an hour after that when he felt the effects starting to diminish, he took another 30mg XR.. he continued this cycle, and within 8-9 hours he had taken a total of 240mg. He was no longer feeling an intense high off them, but was still feeling some sort of boost.

Today, 3-4 days later, he bought 4 more of the 30mg XR pills. He took 1 of them about 2-3 hours ago (with 1 cup of regular coffee) and is feeling little to no effect. About 20 minutes ago, he emptied out the beads of one of the 30mg XR pills, poured them into a small peice of tissue, and chewed the tissue thoroughly until the he could feel and taste them in his mouth. He then downed them with water.

Right now, he is still feeling little to no effects off them. What SWIM is feeling right now may be considered a very, very, very light "buzz".

Note: I weigh approximately 230lbs, so this may factor into it..?

What's going on? SWIM would appriciate some help/advice.
