@SandysMam I know we are all different and react in different ways but truly, the only side effect I've had is hungry at the start, a little bit of weight gain and MAYBE occasionally a tiny shake in my hand an hour after my AM tacrolimus. I'm convinced the tacro makes me feel a bit hot too!
I too was terrified of hair loss, having lost some after a bad (viral) illness (it grew back a few months later). I'm pleased to report that it's not happened yet.
I've asked all my Doctors about it, and one said that it is a common side effect, but it doesn't happen that frequently, if you see what I mean. One nurse said that she's only ever dealt with a handful of patients who experienced it, and she's seen a lot!! 
Hope that calms your mind. The worst thing for me about the meds at the mo is remembering to take them!!! I'm constantly like 'OH NO' then 'phew, I took them'... xx
