These should be given by the clock and administered according to the three-step method: Step 1: Mild pain
Start with basic non-opioid analgesics: aspirin 600-900 mg (o) 4 hourly (preferred) or paracetamol 1 g (o) 4 hourly Step 2: Moderate pain
Use low dose or weak opioids or in combination with non-opioid analgesics (consider NSAIDs): add morphine 5 to 10 mg (o) 4 hourly or oxycodone up to 10 mg (o) 4 hourly or
30 mg, rectally, 8 hourly Step 3: Severe pain
Maintain non-opioid analgesics. Larger doses of opioids should be used and morphine is the drug of choice: morphine 10 mg (o) 4 hourly or morphine SR tabs or caps (o) 12 hourly
• Give dosage according to individual needs (morphine SR comes in 10, 20, 30, 50, 60, 100, 200 mg tablets or capsules).
• The proper dosage is that which is sufficient to alleviate pain.
• Give usual morphine 10 mg with first dose of morphine SR and then as necessary for 'rescue dosing'.
• Gauge the probable dose of the long-acting morphine from the standard dosage.
• To convert to morphine SR calculate the daily oral dose of regular morphine and divide by 2 to get the 12 hourly dose.
• Do not crush or chew the tablets or capsules.

But perhaps just as significantly, it is something that I suffered from for years.
