Yes, I also get some tinittus and popping/moisture in my ears.
I did have heart palpitations and racing pulse previously which also seemed to happen especially after eating - and sometimes after standing up especially if my water intake was low.
for awhile I had to eat extremely small portions, especially if I ate any carbs, like even 1/2 slice of bread I would get palpitations, heart racing and blood pressure instablility (sometimes going high, othertimes very low.. together with exhaustion/sleepiness. I was diagnosed with GERD and extreme scarring of esophogus which was strange because I dont get heartburn, but just some feelings of indigestion (burping). I was put on a medication pantropolol (or something like that) and they did another scope and now the scarring is gone - also no more palpitations or racing pulse.
