Just to ask everyone else, do you ever feel genuinely ill for no reason that you can put your finger on??? I have been experiencing high BS for a few weeks now and have finally managed to get them back to normal range (for me). Took some work but I'm glad I put the graft in, but I'm feeling terrible, no energy and headache, I have experienced it two or three times over the last few weeks, lasts for a few hours and then I start to feel better. So my question is does anyone else experience this feeling?? I'm not coming down with anything, but I was just wondering if anyone else does??? Just wondering if others feel like it, or is it just me, and as my wife says I'm just a hypochondriac!!
