"i&#039;m so sad reading all these great reviews . i am the odd one out i first time i took gabapentin it was prescribed 300mg 3x daily prn for anxiety and i took one and it helped alottle but not much so i waited about 30 minutes and took another i was on cloud 9 nothing bothered me and i slept like a baby . but my dr told me to take 2before bed and that was too much on my heart and i&#039;ve never suffered heart problems on my life 600mg had my heart going so slow it hurt and i had to tell myself to breathe. very scary and even days later i was still suffering complications. i&#039;m too scared to go back to how i originally took it because anything that messes with my heart is a no for me"
