Afternoon naps symptoms and conditions

My 3 year old son was just prescribed Singulair today. After reading the pamphlet that came with the trial pack, I decided to do more research. All of the side effects that most people have mentioned on this post are listed in the pamphlet. I don't know if I will put my son on this medicine but thought I should mention the importance of actually reading the pamphlets that come with your medicine.

Thank God for this site. I thought it was just my sensitivity and exaggeration. I've been on Doxy for 2 1/2 weeks for IBS. Immediately I was nauseated. The instructions were firm in saying to take on an empty stomach, otherwise it wouldn't absorb correctly. None of the side effects websites mention dizziness and extreme exhaustion. I thought it was just me, as I've been so lightheaded and so tired I can hardly function. I want to sleep all the time, but when I try to, it's off and on. I'm up during the night. But when I get up in the morning I feel like I haven't had any sleep. Afternoon naps don't help at all. Nothing, and I mean, nothing, looks or tastes good. I feel like throwing up all the time. I can't stand the sight of certain foods, and don't want to cook because it will make me woozy. I think it's making my already diarrhea worse. I mustn't forget the abdominal cramping.

this is not necessarily a proven side effect but during the time period that I've taken Zestril, I've been diagnosed with refractory anemia. I started taken Zestril in the year 2000. I've had mild anemia for about that same time period. About a year ago, I started having shoulder pain, numb thighs, severe mid-lower back pain, distended stomach. Weight loss. Potassium level increased.
Red blood cell count dropped as low as 31. Diagnosed as refractory anemia. Unknown cause.
All tests were done to check for cancers. All negative.
Erthropoetin shots were used to push the red blood cell count back up again. After five shots, the count dropped. More shots. I stopped taking the lisinipril and my red blood cell count has stabilized. Blood pressure went up to 150. I'm back on lisinipril. Waiting to see what happens next.
Cough yes. Sleepy in the morning and late afternoon naps. Yes.
Anyone else experience anemia since beginning to take lisinopril?

I have just recently started taking Tegretol, recently as in Thursday and it is now Monday, I am very lethargic, and need afternoon naps already, I just moved from 2 to 3 pills a day of the CR type, Thurs - Sat 2 pills, Sunday 3 pills.
