5th day of botched Botox injection - how long until the worsening reaches its peak?

5 days ago, I had my first Botox treatment (horizontal lines on forehead). On day 2, my forehead was already completely smoothed out. Is that normal? Since then, my eyebrows have become asymmetric and worse, my eyes are shrinking continously. According to my research, this common "side effect" will last 3 months to 6 months. I ended up with thick, non-reactive monolids. But how many more dramatic changes will occur in the following days?
