I had no problems at all. My arm where the needle went in is a little tender but only if I press on the spot otherwise no problems at all
Had mine last week. Felt ok but woke up in the night shivering and thirstier than I've ever been in my life. Downed a pint of tonic water in one and 5 minutes later felt fine. Weird.
No sleep, fever and felt like Mike Tyson's been punching my arm and head all night. Hopefully a one night thing.
It will be very interesting on how the second jag will go. Will I experience more of a side effect. Will those who felt bad be ok this time? Only time will tell.
Anecdotal evidence suggesting will prob experience side effects again if did first time, and not if you didnt.
