Emetophobia studies in regard to emetophobia. Victims of the phobia usually experience fear before vomiting but feel less afterwards. The fear comes back, however, if the victim fears they will throw up again. Also noted in the emetophobia internet survey was information about medications. People were asked whether they would consider taking anxiety medication to potentially help their fear, and many in the study answered they wouldn't for fear that the drugs would make them nauseated. Others, however, stated that some psychotropic medications (such as benzodiazepines and antidepressants) did help with their phobia, and some said gastrointestinal medications were also beneficial.
Complexity function applicable, which may be taken to be uniformly recurrent or even uniquely ergodic. For "x" a real number and "b" an integer ≥ 2 then the complexity function of "x" in base "b" is the complexity function "p"("x","b","n") of the sequence of digits of "x" written in base "b". If "x" is an irrational number then "p"("x","b","n") ≥ "n"+1; if "x" is rational then "p"("x","b","n") ≤ "C" for some constant "C" depending on "x" and "b". It is conjectured that for algebraic irrational "x" the complexity is "b" (which would follow if all such numbers were normal) but all that
