When I lived around the corner from you (a while back now), I once woke up very early in the morning (2.30ish) with something very disturbing happening in my chest. I had to thump myself over the heart to get the rhythm back. I thought it best to lay there quietly until I thought it was safe to get up. Of course, like Jo above, my local quack's diagnosis was that it was indigestion. I'd like to think that there are some medics out there who really do know what they're doing. However, I doubt many are working in the NHS. (BTW I always ate my evening meals before 7.30pm....yes I do know how long the digestive process takes and am resentful of quacks like the ones I was registered with).
