Thanks - I was told not to eat anything before and to take the tablet 1 hour before with plenty of water?
Is 25mg all good for you ? how did you come to that dosage?
Thing is, if you are risking a relatively expensive punt, you're probably better off with more than less (unless you are exceedingly unlucky and have a shite reaction). If you get the pills cheap, you can afford to experiment. Then you know if you need anything to settle your stomach / fix a headache or not. A bit like taking vitamin C (the literal sort) and paracetamol before going out on a drinking bender. (By the way, paracetamol is by and large a lot more dangerous than Viagra -- a small overdose can leave you really fucked up for life.) Experimenting also lets you judge the onset. I find it can take slightly longer than an hour and, since it lasts for several hours, you can always leave slightly more than an hour if that works best for you. Any headache pill is ok as far as I can remember. A lot of older men already take something like Zantac (ranitidine), or omeprazole for mild gastric conditions. Both are ok for taking with Viagra (and by anyone who gets wind) but ranitidine also boosts the Viagra and can work when taken a few minutes before sex. 300mg OTC in most countries.
Viagra is an earlier drug than Cialis, and many find Cialis is less than a sledgehammer. I've experimented with large doses of cialis (the biggest pill is 60mg which you need a lot of pussy over the next 36hrs to handle!) I wouldn't take more than 100mg of Viagra in one go. I've also found that if you are getting lots of pussy for a week or so (eg Germany FKK or various long-haul fuck-countries), a regular cialis on the first and third day is enough to keep me going for a fortnight or more. I think the body just gets into the habit of being up for more sex. But for a quick hard-on to punch holes in walls, Viagra is quick and reliable. Of course, if punching holes in walls with your cock is not your thing, try prossies.
