:oops: Not sure where to post this but here goes, if I go out on the steed in a morning I tend to bulk up on the breakfast - either cereal / porridge plus toast, marmalade etc. Now with the exercise & exertion I tend to get acid reflux ( bad heartburn) & so the tablet takes care of this. A few mornings ago going up a hill ,nothing too hard I started to go lightheaded , now there was a runner coming towards me & I tried to move out to let him past & before I knew it I was completely on the wrong side of the road & completely disorientated. Puzzled & recovered made my way home & read the small print, sure enough it was an allergic reaction. Next day same meal -same hill -same time- no tablet - no symptom Hmmmm. yesterday same meal - same time- steeper hill- pill taken - bad reaction- ended up in the dike my mate had to unclip me. The strange thing is that the thought processes never arrived at the default position of unclipping. The pill is the 20mg. dose & no more when riding, had boiled eggs this morning & okay - no light headedness. So just a thought if you pop pills!!
