FINALLY found someone else !!! My case: I have been playing ice hockey 2-3 times a week for almost 2 years now. In April 2010 I started using Rogain 5% (2x day). All summer long (starting sometime in the spring) I have been having serious issues with my endurance which are comparable to when I first started skating. For those of you who've played hockey, took an extended break, then started again, know the 1st few weeks of hell as you build up your wind/endurance. In the spring time I was at my peak endurance, then seemingly overnight, I was struggling like it was week one all over again. This has been occuring at varying degrees all summer. I get winded and weak wobbly legs, a bit dizzy etc... Sometimes weakness like when you get the flu... and cannot get back anywhere near my peak endurance before summer.
** It just occurred to me last night as I almost passed out on the ice that the timeframe seems to directly coincide with my start of the Rogain treatments.
The question now is whether this is a short term effect (ie.. last night I applied Rogain about 5-6 hours before my skate) which can be controlled by not using on days I skate, OR, is this a long term effect whereby I would need to get off it permanently to eliminate this side effect???
Please chime in if you might have any more info or experience here....
