I was concerned that i would be extremely hot and achy and what not. I have been drinking plenty of water and taking cranberry extract pills as well as 200-300 mg a day of B-6. I have seriously gained almost 9 lbs this week. My strength is through the roof already as well. Yesterday was shoulder day and I did much more weight than I have ever been capable of before. If you told me I would already be seeing this much improvement I would have told you that you were a liar. Its crazy. The sides havent been too bad yet either. A few restless nights but Nyquil seems to take care of that. A little irritable but nothin I cant handle. What do you guys think? I would recommend Fina to ANYONE.
