update: lots of washing / showering didn't seem to help. I've got two sims to get married (one is having a midlife crisis and wants to tie the knot) and can't seem to get to a point where both are ailment free long enough. I can see the funny side of this. For me it's a bit too grindy to try and make all the possible apothecary cures, costs a fortune to see the naturopath and also jarring to see loved-up sims suddenly furious (green meanie). So I've uninstalled pack for now as it was throwing things off for me. Would be great if ailments could be toned down to infrequent or have the option to turn them off.
