Yeh, you can be lax with RIMAs. I'm usually only cautious BEFORE the brew, because if there are any adverse reactions they would then come to light while under the influence, which would suck. If you have complications AFTER the trip, you'll be sober and able to deal with any problems.
As to jungleheart's comment, you wouldn't puke it up. The worst that could theoretically happen is that you'd have a hypertensive crisis and die. Most likely, if there were any problem, you'd just have a headache. The hypertensive crisis would probably only happen if you ate and held down a gigantic salami sandwich made with aged blue cheese and washed down with coffee and overripe fruit for dessert, right before/during/after the aya.
