For Anxiety "Neurontin has changed my life dramatically. I suffered from high anxiety with panic and anxiety attacks. I started this medicine at about 19 and had been off and on it the past 13 years. It literally has made me a new person. When I don't use it, I notice a lot of fatigue, worry, anxiety, etc. When I am using this medication, I can concentrate on the better side of things and am not so negative. In the beginning, it did have some side effects such as a 'loopy' feeling. Over time, that did pass, and now it gives me energy to get through the day. I am on 300mg 3 times a day. I can also sleep much easier, and my carpal tunnel syndrome is dramatically better. Before, I felt very snappy and impatient, now I handle things with a much more calm disposition. Love it."

For Pain "I've been taking Neurontin now for 2 weeks, and it does help with the pain, but the side effects in my case are a hazy feeling, difficulty concentrating, feeling sleepy, and I've noticed I'm eating more. My doctor prescribed it together with Percocet for herniated discs, diabetic neuropathy, fibromyalgia, osteopenia, and a slew of other things. It does help, but I work as a secretary for a law firm, which means I have to greet everyone that walks in the front door. I cannot afford not to be alert, and this medication makes me feel like I don't want to or don't care to do anything. So what do I do? I need to take the medicines in order to be able to go to work, but when I get there, I don't want to do anything! Quite a dilemma!"

For Anxiety "I have had general anxiety most of my life, and occasional panic attacks. About a month ago, some personal issues tossed me into a week-long panic attack. I fell into a deep depression that made me have horrible physical pain. I started Neurontin 4 days ago and hours later, I was able to get up and move around. The panic attack stopped and I could feel it lifting. I'm still 'down' but I have things to be genuinely sad about. Today I am starting trazodone to help with sleep. I don't get drowsy on Neurontin. But for me, it worked immediately for the massive anxiety with no side effects except a foggy feeling which I no longer have with doses. The myalgia and pain from the depression is also nearly gone. I'm thrilled."

For Anxiety "My husband is on a 'light' dose of Neurontin (Gabapentin) and the medicine really works to relieve his anxiety. He has Parkinson's Disease and mild cognitive disorder, as well as Parkinson's depression. Neurontin works well on his tremor and his anxiety, but higher doses make him 'foggy.' His dosage is 800mg spread over 12-16 hours, with the option to increase the dose to 1000mg per day, depending on his anxiety level. He has been on Neurontin for many years and it continues to work well for him."

For Anxiety "I notice it takes away anxiety but leaves me a little foggy. It's a great nerve pain reliever for my back."
