If you, like I, take the achievements a little bit too close to the heart, you might have gotten ever so slightly annoyed by the sole existance of the "Obsessive Tea Drinker" achivement. There is not enough replayability to play this game 500 times solely for the gameplay. And, you have to admit it, 500 times is too much to turn off your brain and farm the achievement by hand.

Having said that, I present you a solution to this problem. It isn't really perfect, it isn't as non-intrusive as I wanted it to be, you will have to download AutoHotkey (unless you already have it), but it does the job done, and it does it pretty fast. If you are bad with computers (which you really shouldn't), I'm sorry, but this guide might be not suitable for you. I explained some of the points needing explaining, but definetely not all of them.

Here is the code you will want to put in a something.ahk file:

I respect your security concerns, so I commented every line and provided you with just the code, and not an executable file.

After saving the file, you would want to launch it. Let it do a couple of runs, stop the script (right click the white H on green background in tray and select "Exit"), and check if the achievement counter has increased. If it hasn't, wait for 30 seconds and refresh the page. If the achievement counter still hasn't increased, you will have to increase the delays between actions. In the code they are represented by "Sleep, %number%"

When you managed to get the script working, just wait. With these timings it was done under 17 minutes on my machine. Depending on the amount of plays you already have and the timings, it most likely will take a different amount of time.

That pretty much concludes everything you should need to be done with the achivement. If you have any questions and/or corrections, feel free to leave them in the comments, I'll try to help you and/or fix the guide as soon as I can.

If there will be a need, I will compile the script with higher timings and will attach it to the guide.
