"took 10mg last night for the first time.  felt drowsy after an hour.  thought this was a good thing because i have trouble sleeping, but when i went to bed and started my usual worries, my heart started pounding in my throat and i felt like i couldn&#039;t breath deep enough.  it was a struggle to sleep all night and woke up from weird dreams at 3am and was wide awake.  it is now almost 11 and i feel like i am trembling internally.  i will not be continuing this medication.  i wonder if it is because it is a generic?  i have heard patients have more issue with generics."
