It is possible that the G.I. side effects would have disappeared quickly. I don't know if there is any way to know this in advance. People often experience nausea as a startup side effect of SRI antidepressants - particularly SNRIs. This can last for as little as a half a day, but can linger for a week or more. Vilazodone (Viibryd) is a rather potent SRI. It is 30 times stronger than fluoxetine (Prozac). Perhaps this renders vilazodone more apt to produce startup nausea.
Vortioxetine (Brintellix) is an interesting drug that is similar to vilazodone in some ways. However, it adds serotonin 5-HT7 receptor antagonism. This receptor is currently being investigated for its activity in the etiology and treatment of depression. There may be an interplay between 5-HT7 and 5-HT1a receptors that is important in the ability of vortioxetine to produces an antidepressant effect and improvements in cognition.

Vortioxetine (Brintellix)
Mechanisms of Action
Vortioxetine is considered a new multimodal antidepressant. It has demonstrated antagonistic properties at 5-HT3A and 5-HT7 receptors, partial agonistic properties at 5-HT1B receptors, agonistic properties at 5-HT1A receptors, and potent inhibition of the serotonin reuptake transporter.[6] Of note, preclinical data suggest that these multiple (and in combination) unique effects on numerous serotonin receptors result in regional increases in noradrenaline and dopamine[7] as well as glutamatergic transmission.[8]
