Hello,
Look if you are taking Tab. 
GLYCOMET GP 2 once in a Day &  FBS = 150! You should take  Tab. GLYCOMET GP 2 before lunch. 
Then you need to modify as follows: 
1. Short & Frequent Diet plans to follow. Always have breakfast &  evening snacks on time. 
2. Avoid junk foods &  oily & spicy foods.
3. Include more of green vegetables, veg soups, curd,  sprouts in the daily diet plan. 
4. Cut short dinner diet by 10% &  avoid potato & rice for some days. 
5. Before changing, Drug Doses just check at least 3 readings FBS & PPBS on 3 different days may be on Alternate days whether it's in this range only after following all diet plans.
I would suggest if after all these precautions: sugar levels FBS = doesn't come down to 110 then. You need to modify Drug plans. 
Hope I have answered your query. Let me know if I can assist you further.
Take care
