Two things that can help quite a lot in dealing with withdrawal, although they both have their setbacks (doesn't everything?)
1. Alcohol - At least for me, getting drunk doesn't exactly eliminate the withdrawal, but it makes it more bearable by allowing me to ignore it for the time being, and sometimes helps to warm the "deep freeze" feeling inside you. It also can help a lot with getting a few hours of sleep, but be warned, it has it's downsides. Besides the fact that it's an addictive substance, which means you could trade one addiction for another, when drinking during withdrawal you may feel even shittier the next morning. What I do is get drunk, but not overly drunk, and make sure to drink plenty of water before bed (I always do this when I drink, AT LEAST twice as much water as alcohol I drank) so you don't wake up with a hangover. It's a little tough getting the alcohol to go/stay down when your stomach is upset, but after 15 minutes or so it should be settled (I suggest hard alcohol, as I can't imagine getting drunk off beer, with all that carbonation, would be very friendly on your stomach, but then again I never drink beer).
2. Masturbation - For one it's nice to finally be able to get off, and it gives ya a bit of a "rush" so to speak (maybe not an opioid rush, but it does feel good). Some people say it makes them feel good for a bit, but makes them feel even worse afterwards, but for me it helps a lot. When going through withdrawal, I can easily get off 5+ times in one day.
