neuropathy?

last night, for reasons I'd rather not disclose, I took four welbutrin instant release tablets, followed by three more eight hours later. I was fine until I tried to fall asleep, which is when I noticed forehead tension that was severely uncomfortable. not long after, I started to experience hypertension, extreme anxiety, tingling in the feet and hands, and pain in the hands and arms. this morning I awoke to a horrible headache, and after I took a shower, all the symptoms I had went away. that was only a couple hours ago, yet the aching pain in my arms and hands has returned, especially in my palms. I'm worried that this large dose might have caused neuropathy. If so, I want to know if this is temporary or will it be permanent.
