So this'll be my 6th course of antibiotics .. any suggestions ...

[Twiglett]

I had to take 4 courses of increasingly stronger antibiotics (5 days, 7 days and 2 x 10 days) about 2 months ago for severe chest infection

Now I'm on my 2nd course for a kidney infection

Have an acupuncture appointment in 2 weeks to try to get my system back to normal .. any other suggestions to boost my system?

Poor old you! Probiotics! Lots of them. plus live yoghurt etc.... buy a super acidophilus and keep it in the fridge. don't take with anything hot (eg meals, tea...). SHould help your system to recover.... Also, you could take a super B vit (giant yellow pill that makes your wee turn green...) that should generally boost your immune system etc. Lots of fresh fruit and veg, have a feeling green veg (cabbage, broccoli etc) are best.... Hope you feel better soon!
