Any tricks for getting rid of a tickle in your throat that causes coughing? I've tried tea with lemon and honey, didn't work at all. I'm coughing so much it's making me crampy on and off and that's a little worrying. Cough drops didn't work either. It's hard to get to sleep with this damn tickle and I'm extra over it. I've been drinking hot tea all day and no improvement at all.(It's decaf)
