Hi Dee, I hope that the link Shy left you was helpful? I just wanted to say that since this is the Depression forum you may not get many responses as Nexium is prescribed for acid reflux and that really doesnt relate to this forum here.
Perhaps you could try the GERD - Heartburn forum for this question? Here is the link that that will directly take you to it... https://www.healingwell.com/community/default.aspx?f=45
Good Luck
