Morning
It wasn't until I began Spin classes that my weight budged... I was doing aerobics/Zumba and although I was getting a good cardio workout, the pounds/inches were still hanging on.. Since doing about 10 spin classes, I've already dropped 3 to 5 lbs... depends on the day.. At first, the classes were kinda tough, but once I built stamina , they became easier and easier.. That isn't to say they are easy.. It's just that my body/mind has a better idea as to what to expect.. :)
Also, I try and do carbs earlier in the day.... and for dinner, keep it lean.. veggies, protein... this helps me as well..
As for the sinuses... after a round of meds, could be you don't have an infection.. Have you considered allergies? Also, notice if your sinuses are worse/better at different times of the month.. E.g.... during the Luteal Phase of your cycle, Progesterone is building and therefore, your body warms and hence, the heat can dry your sinuses a little too much and hence, cause any already sinusitis issues to worsen... Then once you have your period and Estrogen begins to build, you might notice your sinuses flow a bit better... Also, try one of those nasal systems.... I find they do a pretty good job when it comes to clearing out the upper part of the sinuses..
Good luck to you
