Question: I am a 46 yo female. I have taken zoloft and xanax for many years with good success. My doc recently tried me on 10mg of Adderall (not the extended type). She told me to play around with the dosage a little. She has since left on a 2 week vacay. I was really nervous about trying it on day 1 and took only a half. I was so tired and couldn't quit yawning (fell asleep). Day 2 took 10mg and again, ended up taking a nap again. Day 3 took 10mg and then a few hours later took a nap. The first day I drank my usual Dr. Pepper and was probably dehydrated. So, Day 2/3, I cut the DP out. I didn't feel as bad, but still don't feel any effects except being tired and not really hungry. I'm 5'3 110lbs and don't have a big appetite anyway. My pharmacist looked at me like I was nuts when I told him I couldn't stay awake. Should I eat before taking it (if so, how early and what types of food). Please help. I'm so discouraged. My son, who is premed was saying hydration is hugely important and I haven't been so good at that, but did try to improve that and I felt better, but not focused and still tired. What would help this med work?
