Should I take Nexium, and do you know any natural remedies for gerd?

I have severe heartburn every day. Surprisingly, my heartburn goes away after I eat, but I do not have an ulcer for which that would be typical. I was prescribed Nexium but I'm hesitant to take it because of the numerous side effects. If somebody has taken it, could you please share your experiences with me, and possibly advise me on whether you think I should take it? Also, if somebody knows any natural remedies that have helped them with heartburn (I'm talking severe here) please share I'd appreciate it tremendously. I have tried Aloe Vera Juice which only helped temporarily, and also am taking DGL which gives relief for only a short period of time, as Aloe Vera does. If you guys just have any additional tips on how to manage GERD I'd be very thankful.
