I have have been having problems with pain issues

My Doctor just put me on Moraphine and I dont know if I am supposed to get immmediate relif but I have tried taking just 1 pill and this did not do anything ton stop the pain My concern is that I am going ton run out of the medication as I will have to use 2 pills at a time 15 Mg each I do not want tpo abuse them but the only way t5hat I am getting relief is to use 2 tablets every 4 hours and that is how they are labeled Why then did he just give me 100 tablets to last me until april the 10th of nest month from my math that is only 4 tablets a day how can I iuse just 4 per day when my doseage is 2 tab every 4 hours and I am having pain in the morning when I wake up and durinbg the day and at night so how are 4 a day going tpo work I will call him tomorrow and ask him aboutb the dose anbd I will need at least 6 or 8 per dayb as bad as my pain is right now I just took minew at 8 pm and its has been 1/2 an hour at 9pm I should be able to tell the differance in the pain level right now I am still in pain. i WILL SEE WHAT THE Doctor has top say tomorrow when I call this is a new medication and maybe he didnt know how I was using the other medication that I was on I had more than enough of the other medication to last me for a while, Som I hope that OI will get this resolved soon it makes me nervious to think about running out of a medication for pain I cant do anything sometimes with the madications now.
