Thanks for your reply. I'm 25. Before all of these health issues started a few months ago, I had absolutely no problems sleeping through the night. I'm also the type of person that can't run on much less than 8 hours of sleep, so waking up at 3 am is not so great. When I wake up it can take 1-2 hours to go back to sleep, and before I know it the alarm clock is ringing.
I have mild to moderate reflux, which has caused grade one esophagitis. I cringe at the idea of raising the bed any higher, but if it helps me sleep, I'll learn to live with it.
I've been eating dinner very early to try to avoid reflux during the night, but I have noticed that my stomach cramps up as it gets close to bedtime. I don't have much of an appetite and don't experience hunger pains anymore, but maybe this is my stomach's way of telling me it needs food. I will try eating something light a little closer to bedtime (but not too close!).
I agree with you about the anxiety meds. I had no trouble sleeping when I was on omeprazole and Nexium, so I guess it could be the Dexilant that specifically causes an issue for me, but I also wasn't taking the Lexapro while on the other PPIs. I took Lexapro years ago for situational depression, though in the morning rather than at night, and I never had any problems sleeping. However, I have read that Lexapro is more likely to cause insomnia in people taking it for anxiety (that's me) than for depression. I think it's odd that a drugs side effects can vary based upon the reason for taking it.
Someone on an anxiety forum suggested I ask my doctor for trazadone (another anti-depressant) to help me sleep, but I really don't want to be on another med just so I can sleep! Also, it seems ridiculous to be on two anti-depressants at once.
