I ended up in hospital on the 3rd with something called Serotin Syndrome.
I woke up feeling a bit crappy and within a few hours I was having really bad muscle spasms and then fits - I was rushed to hospital and they said it was a reaction to the meds I am on - they were very honest as well and told be how dangerous it was - 1 in 8 die from it.  I have never been so scared.
I was ok after about 24 hours and they sent me home - and the shittiest thing is it looks like I wont be able to make it to Costa Rica 
I just hope this isnt a sign of how the year is going to pan out for me.
