to prevent (as in treat it before you take the adderall) dose 300mg chelated magnesium. if you have the sores and want to get ris of them, swish saltwater in you mouth, and drink very cold liquids, if possible, holding each sip in your mouth for 3 seconds before swallowing. Honestly they usually go away after i sleep and my body recovers. Do you redose your adderall? Are you abusing it or using it as directed on the Rx bottle? If you're abusing it, then try not to take more than once dose, youll find that those "sores" will be much less bothersome, and combined with the Mg and saltwater, you should be good.
I find that if you drink enough water ("enough" is a lot more than youd imagine) you get almost no side effects, especially the sores and restless teeth/tongue. The only side effect I got when I did that was insomnia, but to be fair, i hadnt smoked weed in a week, and it made an insomniac during that period, because I cant sleep without it.
Water, Magnesium, Saltwater, No redosing (if you must redose, only do so once, as going beyond that seems to make the pleasurable effects hardly noticable, and the negative effects increase). thats all ya gotta remember.
