Herbal tea is a fine substitute as long as its caffeine free.

It's winter here and you are right it is a bit harder to drink as much. but since making a conscious decision to make sure I drink it, my skin isn't getting dry this year like it has other years. Tea is a great idea, green tea has many benefits as well. The beverages that don't count as part of your water intake are usually things like juices, coffee, sodas

The trick to drinking enough water is to have water with you all the time. Carry a water bottle with you and fill it over and over through the day.
Drink a glass of water right when you wake and before every meal. It will add nicely to your water intake total and also cut down on the amount of food you will eat.

Your goal is going to be half your body weight in ounces of water. if you weigh 200lbs try to drink close to 100ounces. Remember that if you drink a caffein drink, you will need to increase your water intake by that amount because the caffein dehydrates you.

If you like the tea idea, you will be able to find tons of varieties; I have found some incredible teas in my search for drinks to add to my water intake total.

You will notice a marked improvement in your skin with your proper water intake.

I don't like cold water either and am not that much of a drinker of it but I do push myself to drink it, Try it warm with lemon in it. I find that I can drink it much more easily in the winter time if it is warm. The lemon just adds a little flavor and I use that even if it is cold.

Another great way to get your liquids in in the winter is broth-based soups. I have found that they are really comforting and keep me full, and pairing those up with tea and water helps to keep you well hydrated.

I gave up pop, so basically if I want something to drink with meals, I have a big glass of water. Drinking water with meals helps knock out some of the water you should be drinking each day and it doesn't feel like your drinking all day, since it is at a meal.

Once your body becomes accustomed to getting lots of water, it will start to dehydrate faster, because it knows that it will be getting more water soon. Basically, you probably won't find it that difficult to drink lots of water in the winter, because your body will be used to it by then and you will get thirsty more often.
