Took my 1st 2.5mg pen last week and following day had a mild headache
Took my 2nd pen yesterday and all through the night I've had a headache.
Woke up with morning with my head banging and felt so sick. Had a sip of water and immediately threw it up.
Took 2 paracetamol and was literally groaning in bed trying to keep them down.
Went back to sleep till 11.30 (unheard of for me) and now I have a mild headache.
I was thinking this morning that there's no way I'm taking another injection if it does that again :(
