adhd
"I'm 30 and have taken several types of ADD medications since I was young.  I stopped taking Adderall/Ritalin when I graduated from college (about 25 yrs old) because I did not like the side effect, particularly loss of appetite and jitteriness.  I have since had to get back on meds because I have a sales job and I was making mistakes at work.  I started on 25 mg a couple months back and it worked great at first, but has tapered off some.  I wasn't sure if it was still working, but at night when the morning pill wares off and I can't get anything done and I'm super scatterbrained.  That tells me it is working.  I should probably take the doctor recommend evening dose, as well.  Only complaint on side effects would be extreme sleep spells."
