Corticosteroids will break down fat, but then again will redeposit it preferably at the belly, if the calories ain´t burnt.
30mg is supposed to be a high dose, sides are muscleweakness, increased appetite, feeling euphoric, and energized, sleeplessness.
muscleweakeness are supposedly caused by high blood sugar or alike, because it goes away when I´ll find the discipline to workout for more than 1hour, even thopugh I´m lethargic as hell, then it´s gone and I can start to train with more ambition, but it takes a lot discipline and the knowledge, that it´s gonna happen.
In the liong run, depression isnßt unlikelely to occure, because itßs in teh end a stress-hormone and too much of it makes one euphoric first but probably depressive i.e. the 3rd week or so, if one can´t relieve the stress; -cycling for some hours usually does the trick with me and I´m always in a good mood and evens out mood, also;-)
But stay way if you dont really need it and if you do, dont´go higher than the 7,5mg predni equivalent/day or eod = ~50mg Hydrocortisone, =~1.5mg dexamethasone, to name a few.
If you stay with 7.5 it´ll be fine though, IMHO inhalers are just fake and plain rip-off, besides what studies say, it doesn´t help me anything, just sides liek soar theroat and even candida in the pharyny thouzg I _always flushes my mouth, and drank, or ate something. -palin rip-off at least to me.
