A secondary reason for using one needle to draw with and another to inject is that it can take a long time to draw a few cc’s of oil through a 25g. syringe or smaller. By using a lower gauge number to draw with (usually 18-22g.), it cuts down on the amount of time required to draw the oil into the barrel. It's recommended using no smaller than a 21-22g pin to draw with is because bigger pins can damage the rubber stopper after repeated uses, potentially allowing little pieces of rubber to break away from the rubber stopper and fall into the vial. A 21-22g pin is sufficient for quick drawing and will more thoroughly maintain the integrity of the rubber stopper.
Accommodation is easy to find and there are plenty of guesthouses in Soi Buakhao and LK Metro. Many places have monthly accommodation for 10,000 to 15,000 Baht. This can be booked in advanced or after you arrive in Pattaya. However, December to January is busy due to seasonal visitors to Thailand during the Christmas and New Year holiday period. Accommodation per night ranges from 500-1000 Baht. Long stay visitors to Pattaya may consider renting in a Thai apartment. The price is cheaper costing around 6,000 to 8,000 per month including utility bills.
