I suffer from indeterminate colitis, stomach ulcers, gallstones. I have underactive thyroid, fibromyalgia and asthma. I retired early as was getting too much. The reason I’m writing this is that for a VERY long time I have felt extremely ill and started to also get heart palpitations. Any, long story short (!) I am deficient in b12 and folic acid. I have had injections and tablets and the difference in the way I feel is brilliant. I’m not saying I haven’t still got the above but the general ill feeling has more or less gone. I’m coping so much better and don’t feel so depressed.
What I’m saying is please get such a simple thing checked. It’s made such a difference
