Spaceoline

Spaceoline is an indispensable treatment for the various issues a first time space traveler is likely to face. It removes the sensation of vertigo felt in freefall, the resulting fear, and, just quietly, the risk of permanent psychosis that the first two items in the list may create. Many people take it on every trip, just in case, since it is safely non-addictive and 100% effective. It does have side effects, though – users babble in a free associating kind of way.

Spaceoline can also be quite easily altered into a very strong, and very addictive euphoric. It has been repeatedly discovered, independently each time – as the Galactic Service makes a point of squashing the discovery every time it arises.
