"i was on vyvance for just under 1 year.  it worked really well.  however as the year went on my mouth got dryer and dryer, until i could only eat soft foods.  i talked to the doctor and i went off them in the middle of january.   about 3 weeks ago i started a new med called adderallxr and i can feel my mouth is starting to dry but not like the vyvance.  while in the usa i found some mini &quot;brush on the go&quot; toothbrushes made by colgate, called wisp max fresh.  with dryness my teeth always feel like i have a film on them.  today i used one of the brushes and and it really made my teeth and the dryness feel better.  no  need for water or rinsing.  maybe i can cut down on the gum and candy. we&#039;ll see!"
