Thing is paul there are side effects for every drug, plenty of people take aspirin everyday but if you look at possible side affects they can be really nasty but because its a hairloss drug people seem to concentrate solely on the possible negative affects. The % of people who suffer sides are small (like most drugs) but uou should be aware of them before taking them. But the mind is a powerful thing if you obsess about side affects it will increase your chances of getting them.....the mind can play tricks.
