Hello Stacey its good to get to know you. I went CT, and if you have any choice at all in the matter (I did not) I would strongly advise you to think again.It was brutal and I was pretty poorly for the best part of a week.By day 4 I could barely get out of bed.If you are in a situation where CT is your only option ,there are some tips I picked up here that may help you.Immodium melts do whet they say on the pack and for me at least were a must.I also used travel sick pills for the nausea,I am fortunate enough to have prescription strength anti nausea pills but these on their own just did not cut it.I was also advised to get some magnesium spray for the restless legs.Coupled with my weighted blanket did help me get a little sleep.
It sounds like the fear of harming your body is your motivation so hang onto it when the going gets tough.
The thing that helped me through it the most was this forum.When I felt I was drowning the members kept me afloat.We are all here so use us.
Best wishes !
