hi. I ve been taking 30 mg vyvanse for adhd I ve been taking it for the past four days now, since then..I ve been having trouble sleeping I ve only had 2 to 3 hours of sleep... I also been noticing a strange odor coming fromm my urine as well as from my body i feel little bit of pain in my kidneys when i urine sometimes. Never had any infection nor kidney stones. no matter how much water I consume, my mouth is still gets really dehydrated,as if I hadn t drank water in days. im having trouble with my appetite. I don t feel like eating anything , I can spend the whole day without eating and i still wont feel hungry. this is probably a normal reaction to the medication, but if the side effect continues should i wait it out until my body gets used to the medication or should I contact my doctor immediately?
