I have a weird system. I take gabapentin at nite, but will have what I call left over effects all through the day. I get dizzy hours into the day. Have lost balance a few times. No worries, the wall always catches me😁. GP said it called the hangover effect. Call it what you want, but I don't need it happening when I'm driving, walking my dog or in a store. I had to hold onto the shelving until the dizziness passed. That was frightening, & happened hours later in the afternoon. Never had it do that to me before. I'm not giving up driving & walking my pup because of it. If it means I don't use it, I won't. Anyone else have hangover hours later from it? Thank you
