With albuterol I start off at 6mg then quickly ramp up to 18-24mg spread through out the day. I never take it after 3pm because it can mess with your sleep. One dose right when i wake up and another dose before workout to give me the extra boost seems to be optimal.
For ketotifen start taking it after the 4th week of albut. Take 1mg/day and take at night because it will make you drowsy.
