I'm not sure what the hell is going on with me lately. I'm experiencing dry heaves, body twitches, and most of all dizziness when I feel the acid reflux coming up. It's pretty uncomfortable. I started Nexium 3 days ago and it's gotten a little better. I have had bad acid reflux episodes before but this time it's along with the dizziness. At night I'm not sleeping well and in the morning I waked up anxious.
