How did you fail within two hours? Was there still some in your home or did you unconsciously walk to the store and purchase more? Getting it out of your house is key. It's important to raise the friction to act on the vice as much as possible or else you will engage in it without thinking.
If its caffeine you are physically addicted to, I will say the withdrawal is probably just as bad as a nicotine withdrawal. Nicotine withdrawal seemed to hit much faster (for me it was within 15 minutes of my last hit of nicotine vs coffee I just needed it bad in the mornings), but other than that the effects of withdrawal felt the same to me between the two stimulants. In both cases, if you are able to deal with a terrible migraine headache and feeling underslept and sick and nauseous for the two weeks it takes to get through these symptoms (in my experience at least), you will have successfully quit. I have cut back my coffee to maybe 3-5 cups a week (after a long initial detox) and I haven't used or craved nicotine in years.
