Dracaena Marginata - Pls help me save it!

I have had this plant for about two years and with watering twice a month it has been fine. However i have recently moved place and the plant has never been the same since. The leaves are falling off (at the top its almost bare), and the stems at the top have gone soft and are drooping. I think this means that its dying, and i really would like to save it. Does anyone know of a way to save it? If not, will a cliping survive? Please help me!

 

Thanks a lot. I will try that. There are plenty of leaves on the lower stem...indeed that lower area looks absolutely fine. Its the top leaves/stem that have wilted and are drooping. Fingers crossed! Cheers
