"i started the medication jan 9th 2015 at 247 today is jan 31st and i&#039;m down 10 lbs. i&#039;m happy with the weight loss but if my doctor would up me to whole pill i&#039;d probably really lose weight. i&#039;ll see him on the 9th of february and i&#039;m sure he&#039;ll increase my dosage. so far i haven&#039;t suffered any of the side effects previously mentioned. also per my doctor if you suffer headaches it means you&#039;re not eating enough."
