Hello sir, I 25 year male. I am using specs last five years. I checked my eye power before one month. There is no change in my power. But I have severe one side head ache last fifteen days. I checked with eye specialist near my town, he prescribed me clotan for morning, flunarin 10 for night, both after food. Last night I took this tablet, and I am going to sleep. In midnight, I wakedup and I am going to washroom, suddenly I get vomiting sense and I get unconscious, I fell down. I don t know how its happens. This is a first time I got this. Pls tell me what is the reason
