Pounding and rapid heart rate episodes

Hi, I had an issue yesterday when my heart started pounding with a rapid beat rate.I started sweating.I did not experience such conditions as dizziness or shortness of breath or other issues of this type.
I drank 3 beers that night and I was experiencing stress for some period.It happened when I was laying in my bed and heart rate was above 60 bpm.I stood and went to get some water.After drinking it, I heart some sort of clicking sounds of my heart.As I got to bed it started.It stopped after 10 or 15 minutes.
For further consideration, I had issues with my heart making click sounds and the pulse being very strong.The first time I experienced it, I got up from my bed and almost fainted.But for the rest of such episodes, I didnt get up and layed in my bed and the attacks stopped without any complications.Those attacks stopped accuring for a year, but then it happened for me again not being asleep.
Maybe I can get some advices.Thank you.
