Sudden sweating weakness and palpitation

Dear Sir/Madam, I am suffering from diabetes type 2 and htn for the last 2 years. I am taking metformin 500 and teneligliptin 20 (2 times a day) and glimepiride 2 mg before breakfast. Metoprolol succinate 50 and talmisartan 40 daily after breakfast. Due to some health issue last year I was diagnosed with echo and ecg and tmt where every thing is normal only grade 1 diastolic dysfunction. For the last 3 days after 1 or 2 hour after dinner, when I trying to sleep, suddenly I am wakeup with heavy sweating, heart palpitation, leg pain, and shortness of breath. When I woke up after 10 to 15 min I am totally normal Please tell me what should I do? Is that I am going through ecg or echo once again as it's only 10 month had done everything.
