i have read several comments about this, and also to aspirate which i draw 3 bubbles before injecting, however here are my concerns....
after aspirating i start to inject. during the injecting process (my hands naturally shake while not on cycle) is it possible to still enter a vein if the needle moved a little. if it is possible will one know immediately such as tasting it or cough immediately? what if you dont know you were in a vein until you have injected a whole cc? will you die or just cough or get dizzy?
