You find something that works well, you stick with it and things clean up nicely after months sticking to the same thing, then you go to pick up a prescription to be told their having problems sourcing things.

You tell the gp and he prescribes an alternative only for it to blow up and set you back months.

It took months to get things looking ok and this new stuff has reversed things within 2 days.

Ahhhhhhhhrrrrrrr
