Omeprazole and facial numbness

my symptoms were with Prevacid, I believe that these drugs all have the same dangerous side effect. It started with extreme weakness, numbness and pins and needles in my legs and arm. Now after 9 weeks of stopping the Prevacid I feel shaky and tremors. I take b-12 injections because it seemed to have depleted me of my normal b-12 levels. I am hoping this is the problem and will improve . until than my doctor has me going to a neurologist to assure it is nothing else . mri of brain is normal and thyroid is normal. HOW LONG UNTIL THESE SYMPTOMS SUBSIDE , PLEASE TELL ME THEY WILL GO AWAY.

I was on Prilosec for 3 days, then switched to Aciphex for one day. Within hours after starting the medication, I was extremely drowsy, dizzy, and just "out of it." I also have dry mouth and facial numbness. The side effects are pretty incapacitating, and the most distressing thing is that I stopped the meds 5 days ago, yet the symptoms persist. My doctor has run a series of tests to rule out other problems, and agrees this may be a bad reaction to Prilosec. Has anyone ever experienced anything like this, and if so, how long until the side effects went away?
