Gabapentin - and other questions around this

Today I was diagnosed with generalized vulvodynia and I shall start with Neurontin, 1 tablett 300 mg at night. But I am very afraid of the side-effects. I have to drive 2300 km to Southern Scandinavia on June 15th, returning to Hammerfest two months later. And have to prepare the caravan for the travel in a couple of days. No possibility to take a plane. I have cats with whom I travel with. They need special treatment which only I can give them. And the stage on Gotland is more than a holiday. My sister and I have to discuss a lot of issues around my moving to Gotland next year. This cannot be done by chatting and skype only.
Therefore my questions: When I start taking Gabapentin, can I stop when I feel I will not manage to drive to Gotland? Or must this treatment last for a long time?
How long does it take until I can drive? Can I stop taking the drug if it does not work, or the side-effects are still dominant after two weeks. My doc told me that they will last so long.
Would it be better not to take the drug in this situation? My sister cannot visit me. She has the same problems with her cats. None can take care of them.
What are the most common side-effects you experienced? In the Norwegian catalogue I found an aweful and frightening lot of them.
I told the doc of my trip and that I must do it, but he is young and inexperienced. His superviser too meant I should start with Neurontin. But he does not care about his patients. He is brilliant but does not communicate at all.
I feel very concerned about starting a treatment which I cannot finish in case. Or where the side-effects makes it impossible to drive and to work over a period longer than 2 or 3 weeks. Then the pain would be easier to manage than not travelling to Gotland at all.
Thank you all for your opinion.

I'm not sure if this would be available where you live, but my doctor prescribed gabapentin in a compounded cream that I was to use directly on my labia. I would highly suggest looking into having it put in a compounded cream because that could greatly reduce the side effects.

I personally chose not to use it because I know my issue is not nerve related, but my doctor said that some people get to a point of relief and can wean themselves off of it. Unfortunately there are others that are on it for life. I have read that some women have relief for several months and then the pain returns. So everyone's experience is different.

I hope it works for you!
