migraine prevention
"I only used this drug once because I had such a negative experience. I was prescribed this to prevent migraines and headaches, I took my dose at night. It immediately made me drowsy which I didn't mind because I also have severe insomnia, but when I woke up I was still drowsy and continued to be throughout the day. I was also the hungriest I have ever been in my life and I had a headache. It took 2-3 weeks to fix my appetite after taking this drug only once."
