Acyclovir is just as effective as valacyclovir (or Valtrex) but it needs to be taken twice per day (if you take it every day) vs once with valacyclovir. If your doctor prescribes the 200 mg tablets (2-200 mg tabs twice per day for a total of 4-200 mg tabs a day), you can get it at most large chains like Target and Walgrees for $16 per month. You might consider making this switch for cost, but it must be written exactly as I described it here.
It’s very hard to say how accurate a visual exam is. Your IGG value is definitely in the low positive range and there is an 85% chance that it is a false positive, BY ITSELF But combined with a visual exam and your symptoms, it may be more accurate. If you tested again now, a few months later and the index value (the number) is above 3.5, then it would suggest that it is a true positive. Or if you have a lesion you can could have swab tested, that would also be good. The problem right now is the amount of antiviral therapy you have taken. That can interfere with antibody development (slow it). Was your most recent partner tested for HSV 2? What were the results?
