I recently went and filled my usual adderall 30mg prescription ,, however this time I opened the bottle and had some round light orange pills marked U31. I thought I had gotten the wrong meds by mistake but looked on the bottle and the description matched the pills so I then googled it and can't find any info on these new to me, not sure if they are actual new to everyone , adderall. I know they are generic. I'm wondering if anyone has taken them and how they work compared to other generics. I normally take the Barr brand and took my first dose of these this morning and FELL ASLEEP. This isn't good at all. Anyone have comments ???
