yea, that is the issue for me as well with the super kamagra pill. i found that the effervescent is fine. just a little bitter.
for the pill, a little bit of bi-carb in some boiled water. drink it before taking the pill and it helps to alleviate the indigestion and/or the runny tummy. also tried a trustan tablet ( a strong anti-acid) and the pill - worked wonders! The super is really good but the cons can make you really reconsider it at times.

anaconda coffee and the various other coffees on that site work. no side effects.
nasti from the local garage is also good.

but agree with a lot of the other messages - diet and exercise works really well. stress is a big libido killer and my line of work is super stressful - well for me at least.
