Caedmon - definitely. For whatever reason, a dose of 600 mg. at a time really seems to do it for me. It gives me a mellow, happy, relaxed feeling and seems to make talking to people a little easier.
I'm always curious, when a drug works, if a higher dose would work even BETTER. I think I annoy my doctor sometimes because I'm always asking for higher doses of things. I try to explain to her that my theory is, if a drug works, you should keep increasing the dose to see if you also get increased benefits, and if not, or if the side effects are too much, you can go back down. That's exactly what I did with Effexor - asked to go to 225, it made me too tense and irritable, so I went back to 150 and am happily staying there. I just want to know that I've tried every possible route to feeling better. I'd hate to think that I stayed at dosage X and felt OK, when increasing to, say, dosage X times two might have made me feel fantastic.
So, the point of my rambling is, I'm curious if continuing to increase the gabapentin dose would result in an even more relaxed and sociable feeling. However, I don't plan to do this any time soon, as there are a couple other drugs I want to add to my cocktail next time I see my doctor. Also, I'm having serious brain fog, which gabapentin is known to do, and I don't want that getting worse. I see my doc tomorrow and plan to ask for Buspar and Inderal - then when I see her again in 5-6 weeks maybe we'll discuss a higher gabapentin dose. Or maybe not - we'll just have to see how it all goes.
I do find, though, that gabapentin has been very effective for me, so if anyone's considering it, don't let all the negativity towards it on this board influence you. Give it a try and see.
