"i started gabapentin last night; although it was prescribed a week ago. i have very serious allergies and even though the doctor cleared the medicine, i was afraid to have a reaction. i was/am also afraid of the side effects. i am still trying to lose weight after a full thyroidectomy so i don&#039;t want to gain anything else. anyway i was prescribed this for intractable migraines. i took my first 300 mg pill last night as the neck pain i experience prior to some migraines, was riding up the back of my neck. i swear the pain diminished in less than 5 minutes. i did not expect that...weird. tonight i felt the same pain so i took the pill as scheduled. again the pain lessened. i had no migraine today so that is amazing for me. so far so good."
