I'm on 4800mgs a day of gabapentin. 2 600mg pills 4 times a day. I ran out of it early a few months ago and thought I could wait the few days for my prescription to be ready and I was so wrong. The withdrawals were horrible! I felt it was in just as bad as xanax withdrawal. It felt like I was in a constant state of severe anxiety/panic. I couldn't even close my eyes, they felt like they would just spring open. I don't have epilepsy or seizures but I really felt like I was about to seize. It was really intense. It felt like all of my senses were 10 times higher than normal, small sounds would make me jump as if they were gunshots. And it also had all of the rest of the typical benzodiazepine withdrawals. After going to through that for just one day, I'm literally TERRIFIED of coming off of this drug. I've come off of 8mg of xanax a day in the past and also opioids for pain (dilaudid, oxycodone, opana) and also various psych meds. So I have experience in the withdrawal department. This drug is unbelievable. I wish I was warned beforehand of this, I never would have started taking it. I've been on it for about 10 years.
