Hi All! I have noticed on two very recent occasions now, that when I have a black Americano from Costa Coffee, I start to feel a little odd. I have been on decaffeinated coffee at home for a couple of months now, together with being gluten free. I used to love and enjoy my Costa - it was a nice treat, now I am wondering if they do a decaf, I think I will have to change. I feel a little light headed and swimmy, never did, how odd. The first time it happened, I thought it was my own fault because I took my Armour at lunchtime, shortly after drinking my coffee, I was already late taking my tablet that day so had to take it although I knew it wasn't good after coffee/food!! The second time, I was on Thyroid S and I had taken my grains at 6.15am and had my coffee at about 1.00pm. Anyone else get any sensations like these after coffee?
