The shitty sick feeling you get when you're trying to kick a drug, or can't get any more.

The need to hang out with and/or talk to Little Gizmo.

When your smartphone suddenly dies and you call tech support and they ship you a new battery. It takes 3 days to get there and when you put it in your phone still doesn't work and you have to wait 3 more days. You can't put up with it anymore so you go buy a 'GO' phone just to be able to talk.

The sense of bewilderment and pain one experiences shortly after parting with their ginger partner and their adorable freckles.

That somewhat depressing feeling you get after visiting a wonderful country.

When one is so used to wearing the great all around every day clothing item of the hoodie that they often will mistakenly try to place there hands in there front pockets only to find that they are not wearing a hoodie like they thought they were as they are so commonly used to doing where so they in turn look like they just made a strange awkward gesture with there hands around there genital/stomach area which could or could not in certain situations be taken the wrong way.

Strange head sensations, AKA "brain zaps", which is like an electrical current that you can actually see for a split second as it shoots thru your poor unsuspecting brain. Yucky nausea sensation, regardless if you eat or not, kind of like your seasick with a feeling of labored breathing. Just an uncomfortable malaise feeling from head to toe. Trouble sleeping, or not sleeping as sound as when you were taking the drug. Body aches from head to toe. Weird, vivid, violent dreams so scary they wake you up, and then you wonder to yourself, "what the heck was that?" as your trying to catch your breath and come to your senses. A feeling of "this is all hopeless" and starting, or wanting to tear up. Symptoms usually starts within 24 hours or sooner if you stop your dosage cold turkey. Not as bad if trying to taper off slowly, however you may still feel strange at times. Apparently these are signs you really do need the drug...?
