IMHO/YMMV:

Er docs often order full doses of acetaminophen and ibuprofen simultaneously for fever reduction and occasionally pain control. No cross-overdosing, different pharmacology, quite effective: take both. Subsequent doses are skewed cuz acet is given every 4, ibu every 6-8, hours

Aleve/naproxen is longer-acting than ibuprofen, but no more effective. Either can cause stomach irritation/bleeding. Take the ibu, it's cheaper.

You can chew any size aspirin if you are desperate enuf.

dramamine/bonine is a wash. Dramamine puts you to sleep, and nausea is much less troublesome to the sleeping.

H2 blockers-zantac, prilosec are effective and pretty safe. Pepcid/famotidine is effective, safe and cheap.

Alavert et al are approximately 15% as effective as a benadryl. their claim to fame is the non-drowsiness factor. Doesn't matter which one you choose, if any.

pepto-bismol is 19th century pharmacology. Use pepcid et al for GERD. use loperamide for diarrhea, use maalox/tums as an antacid, leave the pepto at home. Enough of it turns the stool black and scares you.

Generic caffeine-only if you tend to dose off during crises. Ups your chances of needing the h2 blockers, antacids, and loperamide, especially if used in conjunction with aspirin or nsaids. Take the caffeine-enhanced snickers bars instead.
