Unfortunately no-one can say for sure, and we can but offer educated guesses based on what we have seen before. I remember I also had adrenal problems and was very weak. I couldn't see an end to it, and Hat told me it would be around the three month mark, and he was spot on. That is when it went. But no-one could have told me that I would still be having seizures a year later...
Bottom line is that symptoms DO dissipate proportionally over time, it is just a question of how long that time will be. I would like to say that after 3 months you will be looking back with relief, which means yes, you are around half-way. But there may be remnants of symptoms which continue to the 6 month, or in my case, the 12 month mark.
Wish I could be less vague, but we are not a forum which panders to those types that say "only positive responses please". These people have their head in the sand and need to know the truth. It is no good throwing false hopes at people. In place, we offer all the support we can muster whilst speaking the truth.
We're here for you the whole way DT... hang in there...
