herbal Schnaps like Jägermeister would help. German Flour soup (boil water while adding in more flour and stir constantly until you have some goup) or Chao/Bubur (Asian rice soup) would be good food (add only a handfull of rice to a pot of water and stir it once in a while while cooking until its also a goup, add vegetables mushrooms shrimp chicken or chicken intestine to it) are good for an unsteady stomach.
These are all new remedies to me thank you for sharing your wisdom @maxdieg! Here they say apple juice, dry toast, plain rice. Yours sounds much more enjoyable!
