Just one perspective
Pigs,
I had a lot of difficulty getting to solo. I was flying after work, around 4 or 5 pm. The air was very rough, bumpy and gusty at that time of the day, I was so busy fighting to keep the airplane straight and level that I just couldn't get any feel for when or how much to flare. So I switched to flying before work, I think around 7 am (I had a flexible work schedule and an understanding boss). Once I started flying in the smooth morning air I picked up the flare within around 3 hrs or so.
I don't know it that has any relation to your situation, but take whatever advice from it you wish. There may be factors affecting your learning that you could find a way to alter.
Good luck!
