Ciplar and beta anxit effects. Normal?

I have been on anxiety medicine on a year now. Recently i get very bad panic attack and doctor prescribed me with ciplar la 40 and beta anxit 20 for 4 months. He told me to if your fear feeling go away and you start feeling weakness then decrease the dose to ciplar la 20. Around 1 month of ciplar la40 , i started feeling weak and unable to walk so I decrease the dose. But one thing is bothering me that i don't feel that weakness now but around the medicine time like i take ciplar in morning around 9 , so my body start acting weird at that time. My pulse rate is fine , i checked it with hand but head start feeling weird. Once I take medicine it comes to normal and this happens on both medicine time. Is this normal ??? Please help me out. I am so scared.
