What do you advise if i'm taking 25 mg of sumatriptan and when i take it i feel like weird, is this normal?

Sumatriptan: Although the sumatriptan represent a marked improvement over previous abortive medications, it does exhibit some adverse effects, the most dramatic of which is the symptom of chest tightness. Other adverse symptoms associated with the triptans are hot sensations, dizziness, flushing, burning sensations, increased headaches and neck tightness. Good luck.
