WOw...Ive been depressed about weight gain, despite healthy eating and exercise. More alarming my finger joints ache so much I've been worried aout early arthritis or Lymes. We thought this was our family miracle after moving to the farm. My daughters seem fine, but I'll be back to the allergist anyway. Most disturbing, the "SIDE EFFECTS LIST" w/ the perscription is very short and lists none of these. I almost didn't even type the search, thought it was all "in my head"! Anyone know if it passes through nursing? My son is high-energy/hyper, but only nurses once daily now. I'm labeled "problem mom" at the peds, guess I should have been more vigilant w/ my own and older kids meds
