I first had botox 3 weeks ago- I had one bruise from an injection site, but that didn't bother me. The worst was the anxiety- I felt constantly anxious and irritable, and I had horrible nightmares every night for about ten days. it got to the point where I dreaded going to sleep. Ten days later the symptoms were gone and I had a smooth forehead but still a wrinkle between my eyes. After a consult with another doctor, I was talked into more botox - I wanted a filler instead. After the 8th injection I passed out. They put bed flat and gave me the rest. last night I felt really tired, and today I am extremely weak. Hope its very temporary-had to call in sick , and waiting for a call back from the doctor.
