Am i supposed to take medications on time? i am currently taking meds in the morning at 8 am and 8 pm at night but not at the exact time.

Depends on the drug: Some medications need to be taken at the same time each day (plus or minus 30 minutes can usually be considered "the same time", for a drug that's taken once or twice a day). With other medications, the exact time is not as important. One should ask his prescribing doctor about his medications, to see which ones are important to take at the same time each day, and which ones are more flexible.
