Eh. While I don't disagree with all of the above, I don't think the issue necessarily has to be with awareness or desire. If you have had success before with lucid dreaming, then it's really not that hard to reconnect with it. Clearly, the desire and willingness is there. It's more likely that your new routine or personal issues have a negative impact on your sleep, at the ordinary physical level. So improve your sleep to improve your chances of LD.
