I hwve tingling and numbness in my tonge plus waves of dizzyness dry mouth. bouts of weekness in arms and legs?

Sounds Serious: There are lots of relatively mild diagnosis for numbness, dry mouth and weakness in your arms and legs, but on the life threatening side, you could be having a stroke, or seizure. I would not spend time guessing, and would seek care immediately. It would be terrible if you died at your computer wondering if i was wrong.

See a doctor: There are multiple symptoms which may be unrelated. I suggest you see a doctor.
