YEs, i have a form of vertigo. My head feels like it's sort of spinning and I have a delayed reaction when I laid down. l There's a more technical term that my doctor called. . But I have been on four cruises now in the past four year, and some have been rocky, but I am ok and did not have a problem.
My vertigo is not as severe as it was several years ago.
My husband has vertigo and we have been on several cruises. His doctor gave him a perscription to take whenhe has a vertigo attack, the drug is Mecclozine. I asked by doctor for some sea-sickness medication to take when crusing and he perscribed - Mecclozine. So check with your doctor and you may be able to take one medication that will help with your vertigo and sea-sickness at the same time. My doctor perscribes half dose pills and to take them a couple of days before you cruise so your body can adjust to any side effects and increase the dose if you have symptoms during the cruise. Good luck.
