"i do not recommend this drug! i like many of you really from what i have read had a great experience at first. i am 26 years old and do sales for a living. i was on cloud nine towards the beginning trail of this prescription. i was able to concentrate more than i had in months and was more motivated to go out and look for new leads for my company. i found that i would get dizzy or a tab nauseous but i found that staying hydrated and always having a water bottle with me helped out. i developed a problem where i would know what i wanted to say but when i went to speak it didn&#039;t come out right and literally made me sound like i was high or drunk. very scary!"
