>>> Is it worth bothering my Doctor with . . . ?
Definitely! You're at FAR greater risk of suffering a heart attack or stroke than someone with 'ideal' blood pressure.
While your GP would almost certainly want to look at the underlying causes of your hypertension (such as the excess weight that you're carrying), his/her first step would almost certainly be to prescribe something like amlodipine tablets. (I'm on them myself). They're definitely 'no big deal'. You simply take one a day and your BP drops to a more reasonable level - and, yes, you can drink alcohol while taking them ;-)
