Random Nausea When Waking

Hi everyone,

This is an AMAZING site, and has helped me with my stomach issues in the past. Long time reader, first time poster :)

I've had GERD for a long time (YEARS!), and it's normally under complete control. I take one Omeprazole (20mg) every morning, and normally I don't have any symptoms at all (its a miracle drug). However, in the last month, I've had three incidents when I wake up in the middle of the night for no reason, sick to my stomach and very anxious about vomiting. I have yet to vomit from these episodes, but that doesn't help relieve the discomfort when it happens of course.

If I get up, sip some water, sit up (instead of recline), and...belch...the nausea goes away. I don't feel bloated or feel like I've got severe gas in my stomach, so I can't quite explain the belching remedy. I'm assuming it has something to do with my stomach, because being upright after a period of time (along with the belching), relieves the nausea.

I have tried finding a pattern to when this happening, but have yet to find one, so my next step is to diary what I eat and drink throughout the day. Has anyone actually had success with finding your triggers with a diary?

I was wondering if ya'll believe that this definitely has something to do with GERD or if maybe something else is going on. I'm getting sick of the nausea which just seems to randomly appear.

Thank you so much!
