Its well over 3 years for me. As usual no one ever reviews your medicine, you are just a number.Likewise, nobody advised me possible side effects but am only on them short term
I do know I have a Hiatus Hernia which causes the problem but no one is arsed. I have little to zero belief* in GP's and the NHS in general, 'Just give him some tablets, he'll piss off then)
*and little respect.
