Blue pills... did they work? Any side effects?

I wonder if with the blue pills it might be the caffeine content causing the headaches? Certainly every time I consider trying blue/ pink pills it’s the prospect of still being awake long after any sex has finished that puts me off trying them.

Do those that get headaches suffer with other types of headaches eg Migraines?

I occasionally get migraines and haven’t tried any pills, so would be put off them if this were the case.
