My Aircraft has problems with extreme side to side shaking at speeds over 2,000mph. I've looked all over for a solution and found that enlarging the horizontal stabilizers raises the shake speed to around 2,500mph. I have no idea how to make it go away and I need help.

due to speed and high pressure try highter or slower :/
Just don’t fly at those speeds.
Flying to higher altitudes should reduce (if not eliminate) the issue.
