Acid reflux help help help?

I was taking omperazole twice a day but had to stop because I have no insurance...its been 2 months and I can't take it no more! I use TUMS and I'm sorry but that aren't worth ****!!!!!!! I think I could get by fine with even 1 omperaozole a day but I'm MISERABLE without it but have not then 105 bucks to buy it without insurance. My tummy hurts a lot I puke my throat burns nasty taste in my mouth eeww I just miss my omperazole! I thought omperazole was same as prilosec??? Anybody know???? What can I do???
