Educated Guesses....

-->Pharmacies and drug companies want to sell as much of the particular medication before the trademark expires so they can capitalize on future drug trails. In addition it is merly consequential that you had this side affect to this particular medication. Try to find the "root" cause of the intrusive thoughts: are there any particular stressors in your life (money, family, illness...etc). Stress can negatively and alter your cognitive abilities.
