What does craving feel like? What does craving feel like as a set of sensations (body and mind)? I'm interested the recognition of craving as it occurs in that moment and how other people's lived experience accords with my own. Also, if there are very different forms of craving that present in entirely different ways.

Many Thanks
For me, craving is obsessive imagination and cyclical replay of a momentary situation in which a key sign of the desirable object is reconstructed by the mind and the sanna (perception or recognition) of the object by the sign occurs. 

This sanna is then extended through a chain of associations into a sequence of memories, both good and bad, associated with the object. Some of these memories bring somatic components, both pleasant and painful.

The basic configuration, for me, of craving is: I am here and the object is there. I can partially recreate the object momentarily in my imagination, but the contact is brief and fleeting, and so not satisfying. This helplessness, or lack of power to bring the object fully and permanently into the now, brings about a sense of frustration. This feeling of mismatch or conflict between imagined object (with its nice associations) and the present absence of it, along with helpless frustration and hopelessness - is dukkha.

Anyway, the key component of craving, for me, is involuntarily mentally being in a different place than the here and now.
