Adderall 20 xr something new? | ADHD Information

I'm wondering if anyone else is having this experience(?) I've been taking Adderall 20mg XR for a period of time. They have worked well for me and I've had no problems. I recently got my prescription refilled and the capsules look the same as always, orange and imprinted with "M.amphet salts" on one end and "20mg" on the other. However when I took one the effects were totally different. All I got was a sore/stiff neck and shoulders and a burning sensation in my eyes. I looked at the capsules and instead of having the 'beads' in them they have what I can best describe as slightly yellowish crystals (like grains of salt or small grains of sand). The crystals have no taste. I haven't inquired yet at the pharmacy but was just wondering if anyone else had this experience.
