Stopping Alprazolam 0. 25 for anxiety.

Hi, I was taking alprazolam 0.25 in the night with dothipin 50mg from last one year. I have reduced dose, I started taking half of the 0.25 alprazolam and now from last one month I'm just taking a quarter of 0.25 in the night as suggested by my doctor so that I can completely stop this tab in future. The goal of my doctor is to completely take me out from these tablets.I was fine for a week,but after that I'm experiencing anxiety rebound symptoms. symptoms are tolerable but I am worried because of these symptoms. Please let me know if these rebound symptoms are withdrawal symptoms.If these are withdrawal symptoms how many days it takes to settle.?   My medical history: The anxiety treatment is going on from last 2 years.My initial dose was half a tab of clonazepam 0.5mg morning and one tab of clonazepam 0.5mg in the night with dothipin.Reduced dose every 3-4 months and came to clonazepam 0.25 in the night.then I was switched to alprazolam 0.25 only in the night.Now the goal is to stop.
