I don't drink coffee too often but when I do, I use some of the RTD vanilla in it. If you are interested in seriously kicking the coffee habit, I have done it. I only, very occasionally, have a cup of coffee now, and when I do, it is decaf. Here is what I suggest:
1). Pick a weekend where you do not have any commitments and if you spent the whole weekend on the sofa, it would not be a big deal
2). Start on a Thursday, and do not have any coffee. Drink lots of water to help keep you busy. You should feel ok on this day.
3). By Friday morning, you will probably be jonesing for some coffee and start to feel a little head-achy, but it shouldn't be too bad. You should be able to get through work without an issue. Keep drinking lots and lots of water.
4). By Saturday and Sunday, you will be full blown into withdrawal. You will feel headachy and fatigued, and most likely crabby
This is why you need to have a weekend that you can just go through the motions. When I did this, I pretty much slept the weekend away. Continue with as much water as humanly possible.
5). By Monday morning you will be on the upswing. You still won't feel 100%, but you will be functional. Each day from this point gets better and better.
Once you are off coffee, it is the most amazing feeling! You will feel energized without "needing" your caffeine boost.
Good luck!
