I was very frightened also. I requested my endocrinologist show my husband and I how to do it in her office. I wanted to be in her office in case I had a bad reaction My husband had to give me myshot the first month. Now I feel silly it really is no big deal. The side effects for me are just lethargy some joint pain but nothing I can't live with. I just pray it's working. I go in for my ckup for my p1np this month. I would advise you get your CTX and p1np BEFORE you start . Best of luck.
