Would these symptoms below be a result of vitamin d deficiency , had same symptoms August last year lasting approx 2 months and has now started again about 3 weeks ago? Nausea, fatigue, hard to sleep, no energy, dizzy, lack of appetite, muscle ache, sore (rough) feeling throat, thirsty (but not frequent passing of urine) constipation but also diarrhea. Could also be Gluten intorrerant/ Celiac (will be esting for this in about 3 weeks)
