Welcome back to the forum.
I'm glad you're on treatment. At the time of your first question, I said the consensus was "moving toward earlier treatment". In the 6 months since then, I would say that the consensus is now clear: everyone with a new HIV infection should be treated, assuming access to regular care and no economic barriers like drug cost.
Your viral load decline is good. The goal is to suppress VL to an undtectable level. That often takes up to 12 months, so you're pretty well on track. In the short run -- on treatment for only 6 months -- is is more important than CD4 count. The average improvement is CD4 typically is slower. Often there is an initial rise in the frest 1-2 months of treatment, but not necessarily; and after about 2 months, the rise averages 50-100 cells/mm3 per year. Also, the rise tends to be slower in people with higher viral loads at the start of treatment. To my knowledge, there is no evidence that life stresses have any effect on it.
So while it is reassuring when the CD4 count rises, your stable count at 6 months is not necessarily a problem -- and all things considered (i.e. with viral load), I am not concerned. However, I definitely recommend you ask exactly the same questions of the doctor or clinic managing your treatment. If your VL does not decline to undetectable, or if your CD4 does rise significantly in the next few months, perhaps they would recommend a different combination of ART drugs.
In the meantime, don't worry. Although the best drug combination may vary from one person to another, these days it is almost always possible to find a highly effective, nontoxic, convenient drug regimen.
I'll be intersted to hear what your own doctor says, especially if different than these comments.
