There are basic things to remember
1. do not drink for 30 mins prior to eating
2. take only very small pieces, about the size of a rubber on a pencil
3. chew thoroughly, it was reccommended to me i chew everything AT LEAST 15 times i know some have been told more. Remember meat will need more chewing then other foods
4. pause between mouthfuls, put the fork/spoon ect down so you have to pick it up again
alternate each foodtype so foods do not easily stick together - not easy when all you can manage is proteins
5. everything you eat should be consumed within 20-30 mins max
6. Do not drink for up to 1 hour after eating to allow for proper digestion and prevent food being washed through
If you are doing these ALL things then you should contact your dietitian
