Seasickness and scuba diving — what works, what doesn't, what to take

In one paragraph

Seasickness shouldn't stop you from diving. The boat ride to Gili sites is 5-15 minutes — short enough that most prone-to-motion-sickness divers don't experience symptoms before going underwater (where the sickness vanishes the moment you descend). Practical playbook: take Stugeron or Bonine 60 min before boarding (NOT Dramamine — it causes drowsiness incompatible with diving), eat a light breakfast (not greasy), sit on the side of the boat with the horizon visible, and avoid reading or looking at your phone during the crossing.

Medications — what's safe to dive with

**Stugeron (cinnarizine)** — most widely-used among divers; effective for 8 hours without drowsiness. Sold over-the-counter in Indonesia and most of Europe; not available in the US. **Bonine / Antivert (meclizine)** — slightly more drowsy than Stugeron, still considered dive-compatible by [DAN](https://dan.org/health-medicine/health-resources/diseases-conditions/motion-sickness/). **Dramamine (dimenhydrinate)** — strong drowsiness; *not recommended* before diving because of impaired situational awareness. **Scopolamine patches** — effective but have side effects (dry mouth, vision changes) that complicate underwater orientation. Try any new medication on dry land first.

Why Gili Air is gentler than most dive destinations

Three structural advantages: **short boat rides** (5-15 min) — symptoms barely have time to develop, **calm protected waters** — the reefs sit between Gili Air and Lombok's northwestern coast, sheltered from open-ocean swell, **morning departures** — winds are weakest 06:00-10:00 when we run most courses. Compare to a Komodo liveaboard where you're on a moving boat 24/7 for 7 days. If you're prone to motion sickness but want to dive Indonesia, Gili Air is statistically your easiest option.

Common questions

I'm really bad with motion. Should I still try diving?

Yes. Underwater is the cure for motion sickness — once you descend, there's no surface motion to track. The challenge is just the 5-15 minute boat ride. Take Stugeron, sit near the back of the boat (less pitching), keep your eyes on the horizon, and you'll be fine for the crossing. Once down, you'll forget all about it.

If I get sick on the surface between dives, can I still do the second dive?

It depends. Vomiting depletes you — if you've been actively sick, your instructor will likely call the second dive (rehydration + recovery is more important than the extra dive). If you just feel queasy but kept your breakfast, sit on the boat with your eyes on the horizon, sip water + a ginger ade, and most divers recover for the second dive. Tell your instructor honestly — no pressure to dive if you're depleted.
