Excess Saliva.....Ewww

Has anyone been suffering from excess salivation? Since I was about 12 weeks my mouth just pools with saliva. It's so disgusting! I'm constantly spitting and carrying around something to spit in! I'm now 22 weeks and still having the same problem. Talked to my ob she said there's nothing to do about it, should go away in second trimester:/ anyone have any tips? Please! Any suggestions? Thanks.
