Omeprazole and six months

I am 29 y/o. I've been on omeprazole for a year now. My insurance wouldn't pay for the name brand. I had the occasional side effect for the first six months like vertigo, nausea, feeling out of body, etc.
For the last few months, the side effects are more regular. I have extreme hot flashes, sometimes to the point I feel like I'm on fire inside. The headaches are more frequent, and one or twice a month, I get migraines.
I can't handle the burn of the reflux because it is so bad, so I have to endure the symptoms until I can see my doctor.
Thank you guys for the input. I thought there was something seriously wrong with me.

I have been on Omeprazole 20 for six months now. Even though I feel better with my reflux, but when I finish the drug and stop taking it, within two days the refux starts again. When I am taking omeprazole 20, I feel pain in my both arms specially when I extend my arms and I have shortness of breath and some time choking even when I am not eating anythings.
