After 8 years sober I still have periods in my life where I have no motivation, feelings of extreme lethargy and times when my head is full of either nonsense or 'fog'. I'm not saying that any of it is particularly down to PAWS but it could be! The difference is recognising when it's 'normal' (even none drinkers/users have days where they don't feel right) and when it's extreme. Like others have said, the feelings do pass and at this stage, please don't worry too much about what the future holds. We all take a day at a time, and we can all ultimately cope with life much better without a drink, even though sometimes it doesn't feel like it. Thinking of you.
