Aciphex and hard time

Hello I am 30 years old and have gerds, I was put on Aciphex 20mg and the first week i felt a lot better, But after the first week I have been having to urinate ALOT! I have had horrible tightness of the chest, I felt like I was having a heart attack the other night! Very scary, I have since quit Aciphex and started today on pantoprazole 40mg! I hope this pill is a miracle! If this pill doesn't work I am just going to work out and eat light.
I would advise anyone thinking of going on Aciphex to be careful the anxiety attacks and hard time breathing is very scary.
If anyone knows about Pantoprazole let me know asap!

I took Aciphex for 1 day and at bedtime I had a hard time falling asleep as my heart kept "leaping" and I'd literally jolt when this happened through the night. Also, got what seemed like a bad migraine head (I usually don't get many headaches at all) for many hours. I'm not sure to try another pill even for the 2nd day after coming upon this ominous but true website. It did seem to relieve some abdominal pain on my left side I'd been having for weeks. I'll have be wise and pray about it.
