I don’t know about antibiotics but you can get morphine solution it’s like cough mixture
It’s really nice
You will have to speak to a doctor

Yes they do but you will find tablets have to be taken whole that’s something to think about as they might not work

The doxycycline I get comes in capsules that you can open and pour the powder into water. I imagine it would taste pretty bad though.

I don’t know but I would say put it in with your food some how

I used to be the same way. Out of desperation, I learned to swallow them. My only other option was an IV. That gets expensive. Some things do come in capsules but make sure you can put it in yogurt or something. Some of the new drugs are time released and it can't be put in yogurt.
