Gabapentin

I was taking 2400mg. For a couple weeks before my legs and feet swelled so I was weaned off and then wound up in hospital for 2 days with shortness of breath. Did all kinds of test and found nothing. When I got home I started to have really panic attacks. Had to go on valium to get settled. I still take 0.25mg 2 times a day. It seems to help my feet also. I am starting back on gabapentin

300mg at bedtime and feel a little enter. But my balance is really bad. I use a cane on bad days.
