Do not use Brittney if you are nursing, pregnant, or may become pregnant. Possible side effects are generally mild, and were not severe enough to prevent people from using Brittney.
Side effects include:
Shallow breathing, slow heartbeat, seizure (convulsions), cold, clammy skin, confusion, unusual thoughts or behavior, severe weakness or dizziness, feeling light-headed, fainting, drowsiness, nausea, vomiting, constipation, dizziness, and headache.
I also do a lot of drugs.
