Thanks for the good wishes. Basically I have a hormone imbalance which, without going into too much detail, causes what my grandmother used to refer to as "woman's problems" lol for weeks on end. When this happens I can sometimes hardly leave the house unless I take progesterone (a common side effect of which can be weight gain).
Anyway, I am going to stay off the tablets for a week and see what happens because I've got a writing week at home. Hopefully I will be back feeling great by then!
Keep up the good work all!
