I finished my 10th pulse with Tindamax yesterday. It was a 7 day pulse. I would say that this pulse was not quite as easy as the previous. Every month is different. This time I don't wonder if Tindamax is really doing anything for me. With my reaction I know it is. I still didn't feel as badly as I did with Flagyli [2] but definitely knew I was doing a pulse this time. As always, I do fine the first couple of days. But by the 4th day I feel like it is hitting something. On 4th day I had a headache all day (not as severe as in the past but still there). On the 5th day I was so tired all I wanted to do was lay around-fortunately is was Saturday with lots of college football to watch!
