Cinnamon streusel latte

I was feeling really bad today. I had to cheer myself up. I went to Starbucks
and treated myself to a grande Cinnamon Streusel Latte and a cinnamon swirl while reading Cosmo. After finishing my cup, I remembered I was to take my meds.... Salbutamol 2mg/tab, 1 tab TID

• A short-acting β2-adrenergic receptor agonist used for the relief of
  bronchospasm in conditions such as asthma and COPD.
• Common adverse effects include: tremor, palpitations and headache.
• Infrequent adverse effects include: tachycardia, muscle cramps, agitation,hypokalemia, hyperactivity in children, and insomnia)

I suddenly had palpitations, tremors and generalized headache. But it actually provided relief of my cough. Do I have asthma? I remember our pedia resident at the OPD when she prescribed Salbutamol to a patient. There conversation was:

Mother: " D po ba pang-asthma lang ang Salbutamol?
Doctor: "Hindi lang naman po pang-asthma yan. Kahit po sa ubo pwede yan. Lalo na po at namamaga ang daanan ng hangin ng bata.

I don't know if I have asthma. Salbutamol has surely helped me with my cough. Somehow, I have less coughing now. Magpa-peakflow kaya ako?
