Dose 3... What can I say about dose 3 except insert a picture of a skull and cross bones? Oh man, this one was a doozy. In fact I had to wait an extra 2 days to take dose 4 because that's how intense it was. Basically it's kind of like every tummy symptom you can imagine happening at full throttle around the clock. That's the only way I can describe it delicately. This treatment is seriously no joke. If you have had a long standing infection of Giardia then unfortunately getting rid of if is no walk in the park. But it just solidified that this was a major part of what has held me back stomach wise and I'm just thankful to have sometning available to me to treat it other than antibiotics. I'm on to dose 4 now, I'll report on that in a few days!
