If you take more drugs sublingualy than can be absoarbed, they just dissolve into your saliva and you'll end up swallowing the rest. So you really didn't waste anything. I see you're new to bluelight, so just to let you know In the future you should include the dosage in mg. We don't know if you took 3 5 mg tablets or 3 20 mg tablets, which is a big difference and could turn from an efficiency concern to a big safety concern. Also, taking something sublingualy instead of orally doesn't effect how strong it is, just how quick it kicks in. Considering it's dextroamphetamine IR, it would probably kick in if you take it orally before it even dissolves sublingualy.
