hi qazafi khan,
Thanks for your query,
your post prandial blood sugar is little bit in the higher range... not to panic for that.. your sexual weakness and body weakness may be due to your diabetes
you need to increase the dose of your metformin
.. take metformin 500mg even after your post lunch.. after 15days you check your blood sugar and see whether its under control or not...
eat some healthy diet for your weakness...once your blood sugar comes normal , you will be alright..
post me for further queries,
best regards for good health,
