I'm taking Metformin and was put on Lantus Solostar about 2 months ago. I have now started on Victoza injectable also. Last night had a feeling of being freezing cold and shaking and had to go to bed. I didn't take my Lantus dosage at bedtime, but did at 1:30am when I woke up after two Ritz crackers w/peanut butter. Then I woke up at 4pm feeling overheated and sweaty. I'm nauseated, no appetite and no energy. (I felt better BEFORE I got this "help"!)
