Have A Day Doc. Im Taking Proton 40mg Once A

Have a day Doc. Im taking proton 40mg once a day for almost 2 months. 3 days ago I stop taking it. Since I stopped it, I feel that my stomach is always empty and feeling exhausted. I have also dry mouth amd feeling dehydrated. I was on my 8 months post op for gall bladder removal. The worst thing Im experiencing is I have difficulties in breathing and suddenly when this attack happen my entire body become cold and shaking like Im out of air. Please advise me Doc. Thank you
