I have question about using this phrase. For example my doctor told me to take 1 pill every day. Then after 3 days he asked me: how long have you been taking these meds?
I was taking them the 1st day, 2nd, 3rd and today 4th day I took them too in the morning and doctor asked me on 4th day how long have you been taking them. I said
I have been taking them for 3 days
but I am not sure since I took the pill today too so shouldnt have I said 4 days?
Should I count the on-going day or still not until its fully finished?
