hello, I have already taken a bit of dex today, i swallow it usually, my question is: if dex is placed under the tounge even just a tiny bit will it have the same duration of effect as swallowing? I am looking for a shorter duration here, I plan to take around noon and swallow it lastsme 12 hours and I want to be in bed before midnight, so bl, the question again: how can i get like 11-11.5 hours out of dex sulphate compressed tablet, sublingually?
