I was at first but not by two months out. Definitely see your doctor. It could be you need to beef up on some vitamins/supplements - but labs will tell you that. Also, your protein level seems really low for being that far out. We were supposed to get at least 60 grams - but then, I know different clinics have different requirements, so if yours says you just need 30-50 grams, then there's that...
being low in iron or B12 can cause tiredness - but again, see a doctor before increasing supplements - getting too much of some of them can be problematic, too.
