Dear Rabbi Shlit’a. If one is very careful not to eat or even drink anything including water outside of the Suka, can he drink water when swallowing pills and medicine outside?

One may argue that since after all he does not recite a brocho for water one drinks for that purpose since it is not meant for deriving any pleasure, so equally it could be consumed outside of the Suka as it is not a ‘drink’. Horav Shlomo Miller’s Shlita opinion is that when possible he should also drink that water in the Suka.
