Nothing worse than having an itch you can't scratch

How do astronauts and other trained professionals deal with itches while in pressurized suits for long durations of time? Does NASA make astronauts undergo "tickle conditioning" to reduce the stress caused by having an itch one can't scratch, or, likewise, the military with fighter pilots? Do the subjects just get used to the feeling, so that the itch deadens? Are antihistamines or similar drugs administered pre-flight? Has weightlessness been found to affect these and related parts of the nervous system that manage sensations of pain, discomfort, heat, cold, etc.?
