Almost immediately I started experiencing the gabapentin withdrawal symptoms: anxiety, fear, trembling, dizziness, insomnia, panic attacks, depression, ringing in my ears etc. I thought my symptoms were from 4 days of the topamax but after having taken myself off of the topamax I now realize what I am experiencing is from gabapentin withdrawal.
