Hi and welcome to Healthcaremagic. Thank you for your query. I understand your concerns and I will try to help you as much as I can.
Well, Reglan is not used for 
bloating actually and this is more like medications for 
nausea. It will not have effect on bloating and some other medications may be considered.
Furthermore, certain degree of bloating  is normal but in case of excessive bloating it may be sign of 
food allergy, hatal 
hernia ,IBS or inflammatory bowel diseases. 
1. So you should do gastroenterologic work up but first try to change your dietary habits, it means: eat smaller meals but more frequently, avoid fried and spicy food, take menta tea, avoid alcohol and coffee, eat probiotics and milk products, boiled food and vegetables.
2.  Also, there are medications such as Flobian,
Magnesium oxide or certain laxatives  which may relieve such symptoms. 
I hope I have answered you query. If you have any further questions you can contact us in every time.
Kindly regards. Wish you a good health.
