Hi every once and awhile (2-3) days. What I call an upper body buzz, the symptoms are the same, I can always tell when it s going to happen, first I get this sick feeling but never throw up, then I get light vibe feeling in my upper body, then light headed for about 60 seconds. It is always the same. The entire session last for about 2 minutes. I have noticed in the past 6 months I have been having short term memory trouble. It scares me at times not knowing what s wrong. I had a heart attack when I was 36 with one artery was block and cleared. Then 6 months later had a pace maker installed. Since then until now never any problems. Thank you!
