Qualifying exigency leave, like leave for a serious health condition, is a FMLA-qualifying reason for which an eligible employee may use his or her entitlement for up to 12 workweeks of FMLA leave each year.
Considerations. You can change your calorie intake during training if you feel it is necessary. If you're gaining weight, try eating 200 calories less per day. Likewise, if your training is suffering and you lack energy, you're probably not eating enough, so add in an extra 200 calories each day.
Also it is good to load up on protein and calories 30-60 minutes after your workout as well. If you can eat about 30-45 min before your workout I would recommend eating a banana and a small handful of almonds (non-salted kind). That way you get the carbs from the banana and some protein from the almonds.
