Hi gemma. I havn’t written on this site yet but i saw your post and wanted to reply. I used to be exactly the same! I over came it a few years ago now but i know exactley how you feel. I used to break tablets in half and put it in yogut!!
The problem is your throat wont let you swallow the pill as you think your going to get into trouble! You wont and you just have to get used to the feeling of swallowing something whole. Try practising with a pea, sounds silly but it will train you to be ok with it!
Other than that just go for it, i know it is hard and i sometimes still find it a struggle but as others say, you will get used to it.
Hope that helps. I have just had my blood tests and providing all is ok i should start soon, i expect i will have the same trouble as you to start with! Good luck x x x
