I used Tymlos for 2 years without any negative side effects, no nausea no dizziness, no pain. I was so nervous the first times I injected myself, but had no issues. I did follow for the first week the advice to sit still for about 5 minutes after injecting because I heard that might prevent dizziness,. After the first weeks I just got up and had no problems Everyone's body is different but I hope whatyou choose works for you.
