"i was diagnosed with adhd 2 years ago and was put on dexedrine and adderall. i recently was in rehab for alcoholism and a nasty heroin and xanax addiction. while in rehab the doctors switched me to wellbutrin which worked well for my adhd but made my hair fall out. i started researching natural ways and now i take about 200mg of fish oil every morning along with vitamin b12 before work. i don&#039;t know if it is the placebo effect or what but friends, family and coworkers have noticed i am a lot more focused and my job performance is a lot better."
