Does anyone have experience with this med.? My PCP gave it to me to even out my mood swings... (that I was just sure were all in my family's head). Anyway, it makes me so tired/sleepy and that's the last thing I need when trying to fight MS fatigue in the first place! Just been taking 10mgs for the past two days but am supposed to go to 20mgs after a week. Will the sleepiness go away? I feel like I've taken a whole box of benadryl!
