Generally the nausea which results from wine is caused by the sugar.
When drinking more than 2-3 cups it is recommended to use either dry wine or a semi (semi-sweet is dryer than semi-dry). Beginners are often recommended to start with a cabernet, though i found merlots to have more of a dead taste which is easier to stomach for those of us who don’t enjoy dry wine and only drink l’sheim shamayim.
Hangovers and alcohol poisoning generally have more to do with dehydration. Always match 1 cup of water for every cup of wine – don’t just down a bottle and hope for the best. In addition it could be dangerous to drink on an empty stomach and to drink in a short time-span (spread it out over the day).
