Unfortunately, every PPI and H2 will have side effects. Lanzoprazole (Prevacid) has a similar structure to Nexium, Protonix, Aciphex and Prilosec (all *prazole; panto-, ome-, esome-, rabe-...) so you may experience the same side effects from all, though you'll only really know by trying them out.
The other two you mentioned are H2-inhibitors, and similarly, they'll probably have similar side effects. However, the only way to know is via personal trial.
You may also want to explore the possibility of using Reglan, though it does tend to have a higher incidence of side effects, so be warned.
Discuss with your doctor what other options are available to you, such as hernia-repair surgery (Nissen Fundoplication).
