I've been riding for a while and put in about 60 to 80 miles per week. I have lost weight and feel better but my stamina isn't where it should be. I hydrate well so that is not a problem. I've never completely bonked but it seems that my legs give out much too soon. Spinning is more tiring than mashing and while hills are getting easier, I lose power before the crest. I can't do a hill without breathing heavily but I can still hold a conversation.

I am a 57 yo overweight type 2 diabetic and have had high blood pressure. My weight is dropping so I'm on the right track. I take the following meds: Glucoyhage, Diovan, Zocor, Niaspan and an Aspirin. My blood sugar and blood pressure is under control.

The question is, could one or more of these medicines have an effect on stamina and/or lactate acid build-up or flushing? I asked my doctor and he wasn't sure and is looking into it. Since some of you are in the know, perhaps a quicker answer may happen.

Thank you.
