Not too well I am afraid

Cannot fall to sleep as fast as before since the past 4 nights or so. This coincide with my readjustment to L9 in 1 caps/day instead of the former 2. Yesterday all of a sudden i got some sort of running nose in the office. Could be the aircond, coffee too much (3x), or the plain water from the water cooler which is no good. At night dozed off at the sofa and feeling ill before going to bed. Now at office still with the running nose. Perhaps i need 2 to sustain and not merely relying on 1 ? Wife testi :- Normal on 1st day felt the energy but thought it could be purely motivation for doing what she love to do - making kuih. 2nd day totally flat sleepy to the greatest extent like cannot stay up to watch desperate housewives. 3rd day feeling ok in fact woke up and start blabbering about my alarm clock not off. Sleepy still there but much lesser. 1 and 2 days = 2caps/day 3rd onwards - 1cap/day in the evening
