Diabetes and gastroparesis

There are just some days I wake up and my stomach feels great, dare I say, normal!!  I can eat and drink anything I want and I don't feel a thing.  Then there are days that I wake up and I can feel the reflux right away and I'm miserable all day long.  I've never had the vomitting or bloating or nausea, just reflux (the feeling that acid is building in my throat).  If I am active all day, it seems to subside a little.  Reglan just concerns me because every doctor I talk to says its safe, as long as it is a small dose and it's only for short term use.  When I ask what happens after the short term use, nobody has given me a definitive answer. 

Do you have any other nerve problems (feet, legs, toes, hands,etc.)? I've been told that gastroparesis always comes with other nerve problems.
