Bacterial Vaginosis woes (read on, may be tmi?)?

I'm at the end of my tether with a problem lasting roughly three years. I've suffered from recurring bouts of BV since the age of 19 (I am now 22). It effects my daily life and self esteem. I know I am a clean person but it makes me feel and smell like I am not. I get respite during my periods (unusual for BV but at least I know what to do during those seven days and therefore smell a lot cleaner). I think I contracted it when I first had unprotected with my then long-term boyfriend (we've split up since, in 2009). I'm afraid to go to the salon to get waxed. I'm afraid to sit down for too long in case the smell wafts up. My panties are often damp after wearing them for a few hours. It's disgusting. I've been to an STD clinic twice about it, and both times got the all clear for other infections and got given antibiotics, which only helped for about a week after the course was finished. I've been using plain yoghurt tampons and taking lactobacillus acidophilius tablets, along with folic acid tablets, over the past few days and there seems to be a big improvement but does this mean I have to continue doing this for the rest of my life? I've met someone new who I really like and who likes me but the idea of taking everything to the next level when I have this condition seems like hell, I can't explain it to him. Even my ex used to complain (before I found out what it was), and so as a result I went through a phase of washing three or four times a day, which in retrospect probably made it worse. I'm 22 now and I've read a lot about bacterial vaginosis and I know that it can cause problems with fertility and childbirth, which worries me even more. Is there a way of combatting it permanently or do I just have to learn to manage it from now on rather than curing it?
