Clarification Needed on Nexito Safety an

Hello Doctor, I had an anxiety attack 3 days ago with BP fluctuations and got admitted. After evaluation, doctors said there is no serious BP or heart issue. I was given Nebicard 2.5 mg and have taken 3 doses so far. Another doctor later checked me and prescribed Nexito 5 mg for anxiety. I have doubts because 2 months ago I took Nexito Plus for a similar anxiety episode (only 3 tablets), and during sleep I experienced cold sensation in the head and sudden waking with fear, so I stopped it. Now I am very anxious about starting Nexito, especially regarding sleep safety. For the last 2 days, I also have severe sound intolerance (TV, loud voices, noise), fatigue, and increased anxiety after the BP scare. Could you please clarify: Is Nexito 5 mg different from Nexito Plus (clonazepam effect)? Is it safe at night if taken in the morning? Will it help with sound sensitivity due to anxiety? Can I start with a lower dose, or try non-medicine options first? Is stopping Nebicard after 3 days okay
