A slump in sobriety is common. Thinking about drinking and thinking about not drinking is tiring. There is a term, "recovery fatigue" that would apply, except I'm not sure what you are doing for your recovery.

I wouldn't call it a life or death craving, just an uncomfortable feeling like something is missing .
This sounds like discontentment with sobriety...not just a hump or slump. And if you aren't happy with being sober, what's the alternative? For many, it's drinking.
Part of recovery is learning to live and love the sober life. That doesn't always happen in 54 days, but you don't want to move backwards either. Perhaps a formal substance abuse program or face-to-face support would help...counseling. Getting checked out for depression.
Good luck.
