see above for info on a pre pay scheme and ask your doc / pharmacy about an exemption - you may be entitled to an exemption depending on why they rae prescribed.
What a stupid question you do not normally pay all that if you need multiple drugs and have a problem paying. Of course if you do not want to take them then do not bother your Dr with your prescription. You can always go private and pay lots more for your prescription and perhaps save a penny or two on the drugs. The choice is yours
