Bismuth subsalicylate (Pepto-Bismol, Kaopectate) – helps nausea, upset stomach, and mild irritation/inflammation.
Dimenhydrinate (Dramamine) – antihistamine for motion-sickness and general nausea.
Meclizine (Bonine) – another antihistamine, similar to dimenhydrinate but longer-acting.
Emetrol (phosphorated carbohydrate solution) – calms stomach contractions and reduces nausea.
Ginger (tea, chews, capsules) – natural anti-nausea and mild stomach-soothing effect.
Peppermint oil / peppermint tea – can help reduce nausea and bloating.
Sadly none of these are great for dealing with SN
