Lie about pain so i can get prescription drugs from pharmacy.

A few weeks ago i had a motorcycle accident where i ended up in hospital. i injured my shoulder so badly that i had to have surgery on the day, surgeon had to replace my dislocated shoulder n insert metal plates n screws because head of the humerus bone was so badly fractured. I woke up after my surgery to this kind nurse handing me over some of these blue pills that looked like little round tic tak lollies and to my surprise the nurse gave me a little wink and a weird smile saying "here goes ur morhine" I was already familiar with the drug n what affects it had, but have never taken it b4. A few minutes later i started feeling drowsy n sleepy. the weird thing is, when i close my eyes to try n sleep, i start having these weird flashbacks n random pictures would appear in my head. its like my body is sleeping but my brain is still awake playing little mind games with me. and then when i wake up i can just wake up in an instance. I also feel kind of drunk n tip Z, which gives me that i don't care attitude. so id get up n go for random walks around the hospital still feeling drunk,sleepy,tired and drowsy all at the same time.Then that's when it hit me!!! i said to myself "i can get use to this feeling, not a bad buzz". Every day in hospital i would be looking forward for my daily dosage of morfine and tramadol like a little kid waiting for his treats of lollies for being good little kid in class. and ever since then to this time now i still take the pills. these pill are painkillers. Today i went into the doctors to see my gp telling him that i sill fell alot of pain coming from my left shoulder when really the pain has stopped n he said becareful this drug can be really addicting. so he would print me out a prescription form for me to go to my local drug store to buy more drugs. now every night before i go sleep i would take 4 pills which is 200mg of this stuff. i get on that buzz every night. i hope i dont go back and lie again because if i do then im screwed for life.
